Okay. I've done this in a few threads but... Okay.
Mass Effect 2 on the PS3 has sold close to 150k units in 2 Weeks of being on sale. It took BioShock 5 Weeks to reach similar sales, and BioShock ended up at over 800k units sold on the PS3.

Mass Effect 2 on the PS3 is the second game in a story-driven Trilogy. The PS3 does not have the first game, a game that released over 3 Years ago.
Mass Effect 2 on the PS3 costs, in the UK, costs £40. Mass Effect 2 on the 360 costs, in the UK, costs £15.
Our numbers for Mass Effect 2 on the 360 are hugely inflated. We had the 360 version alone at 1.6 Million units sold Worldwide by the end of March (After 6 Weeks). In reality, the game had sold 1.6 Million units on 360 and PC combined... With downloads included. This makes it seem like the PS3 version is selling much worse than it actually is in comparison to the 360 version.
Mass Effect 2 360 Sales - Here - Note: Go to the graph, look at WW sales as of Week 6. 1.56 Million Units.
Proof that EA said it's sold 1.6 Million at retail... Xbox 360, PC and Digital Sales combined - Here and Here. 2 Links from 2 big, reputable Websites.
Mass Effect 2 on the PS3 is doing as it deserves to do. It's way too high priced. It's late. It's the 2nd game in a Trilogy. It will more than likely hit 1 Million units in its lifetime.
I see no problem with how it's started.
