I don't follow when you say you "rest [your] case." The use of that phrase somehow implies that the linked article is evidence in support of your case, but I don't see how it is. Are 10* exclusives in one year somehow not enough for you? That seems a fairly reasonable number to me.
(* Really, it's going to be 9, since that list includes a hypothetical Halo 4
. I consider it highly unlikely that 343 will release a game next year. Frank O'Connor is consistently talking about continuing DLC support for Reach
, so I doubt they're going to split focus between Reach
a new game.)
