Well, a lot seems to have been happening instead of the terrain this past year so the lack of eye candy seems natural to me. There was the release of DCS World, the P-51, CA, FC3 and I bet there's been A LOT of work with all these new third party developers. Not to forget all the patches that has come out before and after DCS World.
Why tease with something that's not going to make it well before all these other things?
My humble opinion :)
