I feel the same.
Although, let's both be open minded since we still don't have a whole lot of information yet. There could still be new features (battle frontier, gyms alongside trials, a totally different story that plays out on a strange and unfamiliar path, something like the Pokemon World Tournament in B2W2 would also be great), switched character roles to emphasis the multiverse they're pushing (perhaps Lusamine is good, her children are the villains, or something even more crazy)
There are a few new possibilities that COULD make it a worthy purchase. At the very least I like that the edges of every model in the games seem to be a lot smoother, the music having more bite to it, and the better color pallete for the region itself
