Given that we've always had a 2-3 years' heads-up on new generations of consoles, this suggests that now that we actually have substantial information on the Xbox 720 and PS3, a reasonable time to expect them might be around 2013. Remember, design takes a lot of work, and dev kits don't have to match the end product, merely the architecture. I do remember that older 360 dev kits were available as early as late 2003, and were basically modified PowerMac G5s with Radeon 9800pro video cards.
However, the Wii U has been known about for longer, and given how aggressively things are going with it, I wouldn't be surprised to see it out in 2012. This does mean that Nintendo will go first this time around... Which will be the first time they've done so since the NES back in 1983/5. Every other time Nintendo has gone last in at least in North America, and they've never been first in any market.
We'll likely see the new consoles unveiled at E3 in 2012; The Wii U will likely have plenty of playable examples, while the 720 and PS4 will not likely be playable by those in attendance, but rather more restricted "visual demonstrations," using yet-to-be-finished hardware.
Of course, 2014 is still a possibility for Microsoft and Sony: at least right now, the sales on their machines isn't particularly slowing, unlike as it is for the Wii. (it's the drop in sales that've prompted the Wii U's release) That, and NEITHER the 360 or PS3 lived up to the expectations of their respective makers, both of which assumed they'd take #1. Hence, they want to milk their current products for what they can. I'm pretty positive that the speculation/information on the 720 and PS4 has less to do with Microsoft and Sony deciding that it's time for a new generation, but rather a "just-in-case" preparation in case the Wii U steals their thunder. (as it almost certainly will) I believe their line of reasoning basically has them preparing to follow one of two routes, which will depend upon what happens:
- Wii U releases in 2012, sets sales on fire, hurts 360 and PS3 - In this event, with Nintendo again re-asserting a #1 level in sales, (rather than the slow narrowing of the Wii's total sales lead) would be a death knell to the existing consoles; it'll be vastly more powerful and doing 1080p for all its games, where the 360 often can't even properly do 720p, and the PS3 does 720p, but can't do AA+HDR. This "Worst case" scenario sees Nintendo retain all the advantages of the original Wii, while ALSO suddenly turning the tables on computational horsepower.
- Response from MS/Sony - Get the 720 and PS4 out the door ASAP. Given the likelihood of this scenario coming to pass, it's important that they have a successor ready to go: every day with the Wii U uncontested in the 8th-generation space means substantial losses in sales for Sony and Microsoft.
- Wii U releases later, or fails to reach the sales dominance of the Wii - This is a less-likely scenario, particularly given that it mostly relies on the Wii U being LATE; if it's the first 8th-generation console to market, you can be certain that if it arrives first, it will out-sell any other console out there, until it has a competitor. The only question is by what MARGIN it will out-sell the 360 and PS3.
- Response from MS/Sony - Wait and see, wait and see. The 360/PS3 still have sales potential left, so no reason to throw it away. Keep working on the 720/PS4, since they will have to come out SOME DAY. Retain the ability to launch them as quickly as possible once the Wii U arrives on the scene.
I, for one, will be happy to see a new generation; consoles have been holding development too far back, with almost no developers willing to admit that you'd get better results making games for the PC first, THEN trying to push the console's envelope. (compare the visuals of
Skyrim to those of
Battlefield 3, for instance)
Also, the article's comment about "AI being the battleground instead of graphics" are kinda silly. Graphics got no more extra attention in the 7th generation than they did prior; the only way they MIGHT have had more said is simply due to the wide gap between the Wii and the 360/PS3. It's not like previous generations weren't seen as "advanced," and in turn we'll have a slew of fools looking back and deriding the 360 or PS3's graphics for looking "old." And contrary to what might assume, there'll be a substantial gap between the Wii U and the PS3/360; after all, there was a big gap between the Xbox and Wii, and those two were only 4 years apart (vs 6) and those two also represented far more "outlier" status in terms of their respective generations: the Xbox was not just more powerful than its competitors, said gap was unusually large, and the same can be said for the Wii being weaker than its competitors.
