Yes - the controversy bores me. Other than that, no, not really. The dust has been far from unmanageable although somewhat more prominent than previous bodies. The camera is in the high 6,000's with two wet cleanings to date and none currently needed. Zero oil.
Oh, and no regret. I've been happily shooting through the whole brouhaha and have lost zero shots to dust. I have much more creative ways to foul up . . .
