I'm not expecting stellar sales, either.
Ports are always doing worse than the original, the only exception to this are ported JRPGs. Even with all the added extras most seem just sink away and be forgotten. Without these extras most would do even worse. That's why I hoped for some cool addon for the PS3 version of ME2. Not something killer, because that would be unfair for X360 and PC owners, but something that gives your PS3 ME2 more worth. A figurine of a Reaper would have been pretty cool. Ahh, one can dream. :D
Anyway, I expect sales of maybe 70k first week, and lifetime around 0.8 million.
To comparison: Bioshock did 65k first week and is at 0.74 million at the moment.

Hype-o-meter, from least to most hyped: the Last Story, Twisted Metal, Mass Effect 3, Final Fantasy XIII-2, Final Fantasy Versus XIII, Playstation ViTA
bet with Mordred11 that Rage will look better on Xbox 360.
