Since what I like in my PS3 is the media hub aspect (all media, including video games), I'd go for something like that, maybe it won't be a video game system at all.
I can't see myself buying anything Microsoft. I hate them. I could debate about it longer, but it would look like an endless rant (while being true) and I think that statement sum it up pretty well.
I won't go nintendo, I don't like their games and I don't like what they want the video game industry to become.
So I'd probably build a media center "linux+elisa" style running, and quit playing video games.
I like video games because of the PS2, and the PS3... If they disappear, I probably stop playing video games and go back to my 'before video games' life... and probably won't miss it that much...
I tried to answer the question... now, I really don't think Sony will drop out...
They will know Helgan belongs to Helghasts
