Ubisoft resently released a console game title "Blazing Angles".  As far as I know the game is solely available for X-box 360, a MicroSoft product.  This started me wondering if Ubi and MS could be build bridges and that maybe in the near future we could see a combat flight sim that is a collaboration between the two.  It may not be a CFS4, but something in a similar vain......open ended and expandable.
