EA pulls Crysis 2 from Steam and is available now only on Origin

In a turn of events, EA decided to pull Crysis 2 from Valve’s distribution service, Steam. The game is now available only through Origin, EA’s new digital distribution store. Funny thing is that the Steam version of Crysis 2 was quite successful and we don’t know if EA decided to pull it in order to promote as much as they can their own digital distribution store.
Does this mean that all EA triple-A games will only be available through Origin? Although there are some EA titles still on Steam, such as Shift 2, Dragon Age II and Bulletstorm, both Alice: Madness Returns and Battlefield 3 are nowhere to be found on Steam.
