I think a safe prediction is that Nintendo will be still around. Nintendo is so damn strong, and for so much time! Too bad I don't like their consoles much since the Super NES.
Sega coming back is wishful thinking... I'm pretty sure they won't even though I would still buy their console.
Sony and Microsoft are the big question marks. I like them both, though, and I hope they manage to stay.
I love download-only. I don't like discs, if download-only became the norm I'd like it... but I think it might not.
