Ubi execs openly said that PoP was a test for the viability of releasing non-DRM'd PC games in the current market (aka with high piracy rates) vs. sticking to consoles or DRMing the crap out of PC releases. My guess? Their numbers showed what many expected. Piracy high, and sales low. Now again, that's a guess... but it would make sense. Why release content for a game on a platform where most folks didn't buy it legitimately?
