As others stated: It's either timed exlusive or permanent. MS needs to change the label.
Bioshock said only for PC and 360 right on the top. It is now coming out for the PS3, but near a year later.
Gears of War came out for the PC over a year later.
Mass Effect said 360 only but came out for the PC a year later.
Dead Rising and Lost Planet both came out for other systems OVER a year later.
Amped 3, PGR4, Halo 3, Wartech and Earth Defense Force are still exclusive.
Contrary to what people say, my release copy of Eternal Sonata never had a "Only For" logo and was/still is exclusive for near a year.
Hey, if your willing to wait a year for a game more power to you. But I wish MS would change their rule on "Only for" 360 when most come out for other systems.
Im guessing Star Ocean will be exclusive for a year or more.
Here are the current "exclusives" for the 360 right now (console AND PC wise):
- America's Army: True Soldier (Console version)
- Amped 3
- Banjo-Kazooie
- Beautiful Katamari (Wii version never released yet)
- Blue Dragon
- Bomberman: Act Zero (yuck)
- Bulletwitch
- Chrome Hounds
- Crackdown
- Culdcept Saga
- DDR Universe 1-3
- DOA 4
- DOA Xtreme Volleyball 2
- EDF 2017
- Far Cry Instincts Predator (also a XBOX OG version was released)
- Full Auto (only the first one)
- Fable 2
- Forza 2 and the future Forza 3
- Guilty Gear Overture
- All future Halo games
- Idolmaster (Japan only)
- Import Tuner Challenge

- Ninja Gaiden 2 (for now)
- Ninety Nine Nights

- Operation Darkness
- PD0
- PGR Series
- Ridge Racer 6

So console "exclusives" are harder to find on the 360 unless they are first party. That seems to be the case these days. As always any of these titles can get ported later on.
