Just wanted to add this as a rumor change:
UPDATE: There was some confusion previously over Atari Inc and the Infogrames companies, which are not the same entity. David Pearce was the former CEO of Atari Inc, while David Gardner replaced Patrick Leleu at Infogrames. It is Infogrames that is the possible destination for Mr Harrison, not Atari Inc. GamesIndustry.biz would like to apologise for any confusion arising from this.
