Personally, I define a generation as a group of games on the same system, with the same graphics/engine, and the availability to battle and trade between them. That's where the .5 in Gen 6.5 comes from, as the new Pokemon almost make it a new generation, but not quite.
Also a Gen 6.5 would mean no new starters, just the ones we already know, plus the same legendary mascots (in this case Xerneas, Yveltal and Zygarde)
I'm still hopeful for a Gen 6.5., especially since we could use more Poison, Bug and Ground lines in Kalos, and I think revealing new Pokémon until spring 2016 would be a good strategy, as opposed to the usual "Same game with 2 or 3 new things here and there" approach.
