I'm really not on board if all they do is make the graphics look soopah-doopah photorealistic. It'll make games more expensive, it'll put more developers in financial trouble and - most importantly
- it leads to less creativity and more safe sequels in safe genres. I can also see many developers move to casual platforms (phones/tablets) if that happens. And a strengthening of the indie videogame industry, which aren't focused on graphics.
I don't care about online, I don't care about DLC, I don't care about graphics. I do care about indie support, so hopefully we see App Store-like variants on both new systems.
I don't know what my next console will be. It might be a Wii U (seems inevitable that I'll get one eventually), or a PS3 or 360. It likely won't be a $500 "next-gen" machine, unless they manage to convince me. What might convince me? A plethora of new franchises (that aren't shooters). Won't happen, obviously. The same thing that happened last gen is more likely to happen: I'll pick up a PS4/NextBox when the generation is almost over.
(Speaking of which, when I've got the money I'll likely start a thread and let people convince me which to get: a PS3 or 360
Props to Nintendo for actually kind-of interesting me with their MiiVerse, I could see myself use that even if I loathe the Xbox Live community.
