That's what I thought of when you said it's just a rebrand and a skin with a new back end. I mean lets call it what it is, a new app by the wunderlist team that's more oriented towards integration with Microsoft's existing suite of products. So yeah, Wunderlist is dead. Long live its spiritual successor.

Taken as a whole, these sort of acquisitions/acquihires have not tended to go well for the users of the smaller teams original products. One can argue that their is or is not a net win, of course - but if you are a user of a service like this and really like it, chances are pretty good you aren't going to like what company X does with it after acquisition. Given that, it's pretty unremarkable to hear people say "so much for service X, now A has bought them". On the whole, they are mostly right. Sometimes you get an nice service Y out of it though! Often not a great replacement for the original, but nice nonetheless.

For example, I was a heavy Sunrise user. It worked wonderfully on syncing all of my calendars and showing them all to me in one nice feed with a slick interface. I didn't have to sync my various calendars to one central service and feed all of my calendars to one company. It synced them all to my smartphone, which was a feature I was looking for. Giving all my calendars over to Microsoft... no, thank you.

Thanks; I got a good laugh out of this one!
