hmm. metal gear solid 4? final fantasy 13 (and 14 and 15)? killzone 2? gran tourismo? god of war 3 (unannounced but you know its coming)? lair? i could go on and on? hell, the playstation name alone will sell tens of millions, worst case scenario. i'll eat my shoe... no both my shoes, if we hit 2010 and there aren't at least 50 million ps3's sold worldwide. regardless if wii or xb360 have sold even more or not.
no studio would ignore that sizeable customer base.
MGS 4 has been long rumored to be going to the 360 as well as the PS3. PS3 just lost Virtua Fighter exclusivity, and Namco is expected to go multi platform with the Tekken series as well. Killzone 2? No one is looking forward to that game since the first one bombed and the E3 videos were proven as CGI target renders, and now people have seen what the PS3 is actually capable of (no more than the 360) so they have lost that mystique.
PS3 is losing exclusives left and right because the writing is on the wall and developers know he 360 is going to take this round. They also know that software attach rates are much better on the 360 than the PS3 (or any other console) and they are going where the money is.
Final Fantasy XIII won't be out until mid 2008 at the earliest, and the last Final Fantasy game sold about what? 6 million copies world wide so far on a system that currently sells for $129 US.
I am the biggest Final Fantasy fan in the world, but I won't pay $600 to play XIII ($500 PS3 + $60+ game and tax for both) an there is nothing really big due out before then that is system exclusive.
I too could go on, but in short, you are dreaming. You might want to start sautéing those shoes now so they are edible when 2010 rolls around. Ps3 will never even sniff a number like 50 million sold. If it turns out you are right, you can pass ME the shoes
