Would suck if they'd change the name.
I don't believe they will though. It's not likely that Blizzard's trademark attorney (Rigole) did not know of the other trademark, before filling Blizzard's. If the priority trademark is indeed regarding this app, then Blizzard can probably easily negotiate with the owners to drop it or whatever other legal steps need to be taken. They probably already have and this is just a small, expected, bump.
I don't think it's going to be Blizzard Dota all over again, as negotiating with Valve is obviously harder than with the owner of a semi-active, obscure and very niche iPhone app.
