Much as I'd love an official MP Hound I have to doubt any news on and around April 1st as there are way too many trolls out there posting fake news "for teh lulz".

Some people are saying it looks like Universe 2.0 Hound so perhaps this is just a reissue of that figure rather then a MP Hound.
Just have to wait and see I guess.
