I'd rather just have a re-release of the Marvel Select for a few different reasons. First, the Select version was just about perfect in sculpt, proportion, and paint. The only real advantage a Legends release would have is articulation which, frankly, I don't think Uatu needs. He pretty much just stands around ominously. Yes, he's not as big as he should be, but a Legends BAF isn't going to be any bigger, and the Select version currently scales big enough to make the point.

I'd much rather the precious, precious BAF slot go to someone that needs it more like Annihilus or the Awesome Android.
