Unconfirmed: Mass Effect Trilogy Coming to PS3

BioWare's exclusivity deal for Mass Effect is still ongoing, but the buzz of an almost inevitable PlayStation 3 port is growing louder. Second Story Gamer adds to the rumor mill:
A fairly reliable source close to Electronic Arts tells us that the sequel (and subsequent iterations) will be available the PlayStation 3 as well as the Xbox 360 and PC. According to our source, EA decided to make the series multiplatform mostly due to (the economic outlook).

Our source claims that because of the current state of the economy, Electronic Arts is looking to squeeze as much money from its portfolio of games as it possibly can. Obviously, making Mass Effect 2 and 3 multiplatform would increase their sales, as the game would be available to more people.

But what about the PS3 owners who missed the first game? Our source says it is (likely) EA will release a PlayStation 3 port of the original Mass Effect, debuting sometime in mid-2009. Similar to Take-Two's decision to make a Bioshock port on the PS3, this port would introduce PS3 owners to the series and give EA almost risk-free profit from its sales.

The official announcement will (take place at GDC) (which starts March 23), according to our source. Of course, take this with a grain of salt till then.
The "purely economic" argument is an odd one; it's not like Mass Effect did not come out on PS3 for non-economic reasons; exclusivity deals can be profitable as well. But still, with the platform's install base growing, this should not come as a surprise to anyone.
