This looks awesome. But I'm still going to laughing at how silly the name looks while written. "Adobe XD" it's hard to in-see the hilarious laughter emoticon once you see it.
Sketch has a great share of mind right now, and they managed to do what people needed the most in a really easy way, but there's nothing really attractive about it that can't easily be replicated (hence the number of clones out there).
It's more about the concepts it adopts rather than its execution. In my personal opinion, Sketch is Really Bad Software, with some many UI problems and discrepancies with features tackled on nonsensically that it baffles me it's not considered beta.
It's popular because everybody uses it, and everybody uses it because it's popular, but once a more solid solution exists, I think they're going to be in a pretty bad position.
Adobe has its own woes and has produced plenty of Really Bad Software, but they've been at it for so long that if they're really focused and put their brightest to the task, there's no stopping them.
