Well one of the highlighted games from last years E3 is officially dead, or at least dead in th eyes of Microsoft. MS killed the project for vague reasons.
Odd part is, in their press release they mention Rare by name for really no applicable reason. Give it a read, the reasons don't really make sense. MS neds to realize that Rare is only one developer. They are very good one, but still.
