This may not seem like a big deal, but Activision Blizzard is the largest game publisher out there. So their president saying they may stop developing games for the PS3 and PSP is a huge deal.

I’m getting concerned about Sony; the PlayStation 3 is losing a bit of momentum and they don’t make it easy for me to support the platform. It’s expensive to develop for the console, and the Wii and the Xbox are just selling better. Games generate a better return on invested capital on the Xbox than on the PlayStation…When we look at 2010 and 2011, we might want to consider if we support [PS3 and PSP].
