Uh-huh? ...I can't account for this thread's lack of taste.
Seriously, Bethesda's games epitomize some of the most boring, inept, tripe-for-design I have ever had the displeasure of experiencing. No way is Zelda taking notes from those games. No. Fucking. Way.
As for this article, I'm afraid it has little substance to offer. As others have pointed out, the author appears to take for granted that the solution to Zelda's presupposed woes is to make the series more like Fallout 3. Well, that's nothing more than a case of begging the question, as the author doesn't seem to bother explaining why Fallout is the one template of all that is good design in adventure-rpg-style games, nor why Zelda specifically should follow that template. Personally, I "know" Fallout 3 had less substance than any of the console Zeldas, so I don't see how the series would benefit from it at all.
As for the OP's claim that the Wii couldn't handle a more "sophisticated" game, that's rubbish. What do you know about game design - about game history? I study game design, but even if I didn't I would know that "more dialogue" is not a resource-dependent feature. I mean, other than the pre-adolescent suppositions of the kind that made little children think the PS2 was the most powerful console last gen, was there any basis for this claim?
