They'll be ok in the end. Yeah this whole situation sucks for them (and PS3 owners overall) but I highly doubt they'll leave the console race. And I know some people are saying that if they do leave the race someone else will just take their place and here's my opinion on what I've heard some people saying.
Sega: If they did get back into the race I wouldn't mind and would actually be a little pleased, but given how they've been for the past decade I highly doubt they would go back to making their own consoles now.
Atari: Come guys, people stopped caring about Atari consoles after the 2600, do you really think they of all people will try to enter the console race again?
No, if there is a new contestant in the console race, my money is on a company who hasn't made a console before.
