Afraid neither of us have a say in the matter. I'd rather they focus on making the Mac more efficient with the resources given, maybe beef up their software offerings that they already have, but I'm not head of OS X development.
It will continue, though.
They should be focusing on iWork, which hasn't been updated in how many years? 4.
Instead, they've switched to a yearly release schedule, so that they can make older yet still capable Mac's obsolete faster.
