There's already been some to think that Postal III being pushed back and its unknown Linux fate being some early April Fools' Day joke, but unfortunately that's not the case. You won't find any April Fools' news items on Phoronix, but if there were some "crazy" Linux announcements, what would they be?..
an aposid gnome version...yeh, that would be cool. (or just a .deb based rolling-release distribution).
a game like ET:QW but with an unlock-system (like Battlefield) for weapons/techs and lots of players
a semi-realistic ego-shooter (americas army like), set to the future (for laz0rs pewpew) with campaign mode, awesome graphics and vehicles (maybe weapon unlock-system (like Battlefield, yes I like that))
Visual Studio for Linux (gosh, I would even pay for that) with mono implementation (monodevelop is not even close to that)
yeh, that sums it up pretty much. and yes I would get a nerdgasm from any of that.
