From next-gen.biz:

Microsoft's Aaron Greenberg says "the days of Sony snowing the consumers and the press are over," that the company has failed to deliver on numerous promises, and challenges Sony's latest European PS3 sales figures.

"We have been fighting Sony's promises from the day we entered the market," Greenberg told Destructoid. "Three years ago at E3 they showed what PS3 games would supposedly look like with the Killzone 2 video, that we are now learning will ship four years later. That means that we will have shipped Gears of War and Gears of War 2 before they can even get Killzone out the door.

"Think back to GDC 2007 when Sony promised to leap ahead in online with the Sony Home unveil. Here we are two years later and multiple delays for a product that appears to have little to no buzz. Where are the achievements? The friends list integration across all games? Where is the long-promised video store? Where are all the other products using and networking with their CELL chip? How come Blu-ray did not result in better games? What happened with Sixaxis and rumble? Where is the complete 1080p game library we were promised? If Blu-ray as they said would be such a catalyst to PS3 console sales, then why have PS3 sales over the past couple of months not seen any lift since the format victory?"
