right...does it sound logical for them to stay quiet the enitre year...and then announce nothing big at E3?

riiiiight

The only 360 games that interest me are Alan wake and Splinter Cell and mass effect 2 (not on the list)


note: Ninja Gaiden is already on xbox. who cares if it has a little bit more content

Alan Wake and Splinter Cell Conviction is on PC so it don't count as 360 exclusives. Lost Planet 2 will mostly be on PS3 too.

Halo Wars (could be on PC soon so I heard)
Halo ODST
Ninja Blade
Forza 3
Star Ocean 4

So the 360 may only have 5 or 7 true exclusives this year but not all games are annouced yet so it could grow. The PS3 got more this year.

Its unfair to say that its not exclusive because its going to PC.  Alot of microsoft games do.  There still not going to ps3 so who cares

 That list surely is impossible to beat! The X360 has already a fantastic lineup in 2009.

Don;t forget mass effect 2

I wouldn't say impossible to beat, I had to add 2 unannounced games and a timed exclusive to pad it up a little. Still a solid list though.

But I can still play those games if I have a PC and not a 360. So where's the exclusivity?

 Yes yes, but then you also forgot Risen. Since Oblivion is the greatest of all time, Risen should be pretty solid (since it seems like a good attempt of an Oblivion clone).

Microsoft will announce BioShock 2 will be have a window of 360 exclusivity this fall at E3. 

Just a guess, but pretty consistent with how Microsoft operates.
