JStevenson, one of the developers of Resistance 2 just confirmed at NeoGAF forums (linked above) that there would be new 'ingame' images of Resistance 2, which would be posted tomorrow.
Here is what he said:
I'm exhausted, but we showed co-op, SP and MP... some folks played co-op for close to two hours, others played SP for that time, and others played MP. We went for over four hours and still had to kick people off.
Feedback was universally and exceptionally positive.
I'll be on a plane tomorrow when everything breaks. Rest assured i'll be around to answer questions when I get in.
