I feel that ORAS would likely end up being rushed. Thanks to the new game releases. ORAS comes in 6 months. Yet we know like 3 things for the BW2 arc, and like 6 things for XY. Needless to say, 6 months isn't enough time to finish either arc (unless BW2 is 50% done already, which would suck because that would make it super rushed). So by the time ORAS is out and the creators are trying to dance with 3 arcs at once, Z/whatever would come out relatively soon as the third/whatever for Kalos, thereby creating another arc that needs addressing. Kind of like how Pt, HGSS, and BW were being handled all at once. And we all know how that turned out.
When all else fails, nothing beats a swift whack upside the head.
