Hrmmm everyone else seems to be having alot of fun making crazy ass predictions so I'll make a few.
From Jan-Dec sales totaled, PS3 will have outsold the 360 3-1
Wii-Fit it going to be a massive flop in America, (kids and American's don't want excercise ;) give em guns! )
SSBB Will sell to everyone who already owns a copy of Melee, and 1 other person. So whatever melee's totals were + 1 >_>
Killzone 2 is going to be the greatest thing since sliced bread and will get a world wide holiday named after it, as well as it's own country, it will be a sectioned off area of the Sahara named Helgan.
Metal Gear Solid 4 will Sell a million copies day 1 and sell 333,333 PS3's.
Sony will find another way to downsize the cost of the PS3 so when MS pushes for an actual price cut around the time GTA4 is due Sony will laugh and cut it down a significant ammount as well.
This is fun :D
