My first thought on this was: Team17 publish stuff too now?
But yeah, I can see that this is partnership is more focused on taking the publishing hassle off Playtonic and on to someone else, allowing the devs to focus more on the game. I'm no backer, but I'm sure if you read the statement then you have no reason to feel swindled, its not like they said "Hey we kinda blew all that money you guys gave us on pretty cars and fast whores, so we sold out to soul sucking suit of a company, i.e: a publisher. Look forward to Yooka-Laylee, but be sure to preorder to play as Yooka!"
