Yes it is possible DH.
I think people are questioning IGN's reliablity because they don't want to believe it.
While Rare's games are good they do then to take a little while to get on the shelves.( it looks like the same for SK as well, but time will tell)
Besides what is everyone worried about?? The worst that could happen is Rare decides not to develop for GC at all.
(hehehehe maybe I shouldn't have said that)
