Although I'm excited to see the reveal of a new Pokemon game (which I think might come at E3 (For a 2016 release??)), I'm also glad they're waiting a year. The thing I want is for Pokemon to suffer from franchise fatigue, and that's already a danger, but the yearly release schedule is pushing it. Plus it will give them time to hone their 3D engine, as well as sort out some of the problems from XY/ORAS.
As for the other discussion, I much preferred ORAS, as I loved the Devnav, flying, and, of course, my nostalgia for Hoenn. Plus, the legendary hunting was a great way to make legendary Pokemon feel mysterious, and bought back (for me at least), the thrill of finding out where and how to get each legendary.
