Most gamers (especially console) don't even read the forums for the games they play.
This is usually true, not many people use forums, but when you can type in "Lag problems in a PS3 game" into google and skyrim pops up at the top of the list....word gets around, and has. I found the forums, searching for a way I could help the issue at home.
As for the other comments regarding the older systems might be partly to blame. This is completely out of context... if you can play any other games on your system and not have these hard freezes like skyrim offers, then the problem is not your console. The problem is infact Skyrim, or rather Bethesda. The only people that have not experienced the severity of these drops in frame rate are only those gamers that have not acquired that large of a save file. You will NEVER see anyone say they have a 16MB save file and have no problems...that would be a blatant lie.
IGN, TGDAILY, TIM CLARK, DIGITAL FOUNDRY.... all these game review companies are extremely disappointed in Bethesda, and you as consumers, should be also. Do not let Bethesda fool you into thinking "it's not that bad" or "not all users", that is downplaying the severity of the issue. I can assure you that if this was not a HUGE deal, that you would not see IGN making Comments with a heading like "WTH IS GOING ON BETHESDA?!"
GOTY (Game Of The Year) is on the line for Bethesda now, and IGN and Tim Clark have stated that if this is not SWIFTLY addressed they will not get it. If Bethesda does not get GOTY for Skyrim, it will not only make all the new staff that worked on Skyrim look at fault, but will put a blemish on the veterans, the Game Engine, and Bethesda's name itself.
Brand Loyalty is a major selling point for Sagas like Elder Scrolls, all you need to do is keep complaining.....and do ALOT of it. The more everyone does, the faster you can see them addressing the actual problem, and not putting it on their "to do list" as they release general post-release patches.
