Releasing pre-existing textures could be it, I suppose. The fundamental issue is that Bethesda just don't have the time to recreate new assets for 15% of their gaming demographic.... But you are right: Textures are made high-resolution and scaled back for the consoles ... so logically it COULD be that as it doesn't actually interfere with the DLC creation process.
Interestingly, polygonal counts are also reduced for console hardware limitations, so Bethesda could theoretically include better meshes. (The originals).
The textures used in the game were originally much better quality. When doing artwork, sometimes they are 4096px.
Basically, they ran a batch process to reduce all textures for the consoles. Modifying by hand any in optimization efforts.
Basically, the number one complaint is probably the blurry textures for the PC version. One person claims they were even upscaled versions of the already compressed console version, which is pretty shocking.
Anyway, it makes sense that it is a texture pack due to demand and how easy it is to do. It takes very little time on their part to select all of the original source textures they used in the game and run a resize batch process on them.
The game was ported quickly due to time constraints. Because of performance issues early on, and because the textures had already been reduced and optimized (make this texture large, and this one small), it provides insight in the reason they just left the console versions in the game.
It also makes sense to make them available for those who want them at this point in time. I've said it before, they should have used a double DVD for the retail Skyrim, giving more room to fit the higher textures.
I doubt they will give 'massive huge ridiculous you need $800 video card' versions, or different size versions (2048px versions and 4096px versions of the packs). But it would be nice. I like to do my own optimizing, and would like the larger ones for my future PC, a few years down the line.
As I have said since the game launched, the textures in the game are fantastic, but they are really blurry and low res. This is basically one of the most disappointing things for me about Skyrim, shallow as it might seem, I just feel like the game is damaging my vision and making me need glasses. So, I would be very grateful for the texture pack, and [not really in this thread] a lot of you have some entitlement issues you need to work out. You bought the game, they don't have to give you better graphics packs. If you were my kid, I would turn the car around, no ice cream for you.
