Not bad considering the bad taste left from Resistance 2. Most word of mouth for 3 I see is pretty good, and given it got to 1M in that time-frame I suspect it'll plod forward to an final figure that's fairly decent.
The SP was pretty decent I thought, although I haven't touched the MP much as I've got too big a backlog of games I working through. Hopefully it won't be a ghost town if I check it out later in the year.
Try to be reasonable... its easier than you think...
