Greninja will most certainly be OU
I feel like Delphox will have to compete with Pyroar for a spot in UU, but it did get a pretty good deal this gen, being one of only a handful of Fire types to have decent attacking stats AND speed over 100. And it got a pretty strong movepool as well. I definitely thing specs or LO Delphox will be a threat.
I honestly see no reason to use Chesnaught over Virizion or Breloom. I'd say RU at best.
The Kanto starters on the other hand all have a pretty good chance of OU. The only question is which are worth a mega slot. (Zard and Saur each have niches w/o Megas though)
