Linux Desktop? Nope. Desktops are dying anyway, almost everyone has moved to laptops.
This is unfortunate. Ever since I became a nomad (and switched to Apple) that I miss actually shopping for desktop hardware. Every time I enter a retail store and look at the high-end video cards I really really want to build a desktop, but it can't fit my luggage... The desktop PC is far from being dead and I am already missing it, I think it's gonna be one of those things that I will remember from early 21st century just like I miss tinkering with analog electronics in the 80s (no, I'm not old, I was born in that decade).
Year of the Linux game console, perhaps?
Rumor has it that Valve is building a console with PC hardware, so I wouldn't rule out that possibility. They feel that the Windows and Mac App Stores represent a threat to Steam as a third party, so this may be part of their strategy to build a platform of their own. Blizzard has expressed similar feelings, which makes sense if we consider the rumor that they had and probably still have a third party service like Steam planned for battle.net (at least according to the leaked schedules which have been quite accurate, though battle.net third parties is overdue at this point).
