The mystery surrounding what Greg Canessa, former PopCap VP and Xbox Live Arcade general manager, will be doing at Blizzard is over. He'll be involved in a revamping of Blizzard's Battle.net accounts service as project director.

News of Canessa's departure from PopCap in favour of more hardcore climes emerged earlier in the week.
