Bear in mind there's a degree of saber-rattling to this, but still; Activision boss Bobby Kotick has warned Sony that his company - the world's largest third-party publisher - may cease support for the PS3 and PSP.
Speaking with The Times, Kotick said "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".
Subtle. But wait. It gets subtler.
"They have to cut the price, because if they don't, the attach rates are likely to slow", he continues. "If we are being realistic, we might have to stop supporting Sony...When we look at 2010 and 2011, we might want to consider if we support the console - and the PSP [portable] too".
In that absolute worst-case scenario, that would mean no Call of Duty for Sony consoles. No Guitar Hero for Sony consoles. No Tony Hawk, either. It probably won't ever come to that, of course, but Kotick's words are still worth noting. After all, when was the last time you ever saw a third-party publisher so openly threaten a major platform holder?
