I don't want to be nitpicky, but there's a misspelling in the OP. You say Uncharted sold 0.91k (and k's on the others too), it should be 0.91m, since 0.91k would be only 910 units 
.
Anyway, it's good the Vita sales have been adjusted here, but personally I don't see it come close to 40m. It's doing Dreamcast levels and several games that were supposed to do it so far have failed to pull sales out of the lower regions. Sure, it's base seems to have been raised a bit for now. Unlike the Dreamcast though, which got it's 10m lifetime sales in one and a half year, the Vita will have a full lifespan. Sony will likely be able to keep supporting it.
I'd say it tops out at 20-25m. So, XBox levels.
