No, I haven't seen it all yet. I read about the IMAX Enhanced version recently, but I didn't see a time frame. I've thought about waiting to get that one instead of the 4K Atmos version for the IMAX Ratio (I'd rip/remux DTS:X instead then). I'm thinking about getting a 2.35:1 screen later this year, though so IMAX Enhanced wouldn't look as good (it'd be smaller on that size screen at home) in that case. Ah well, I'd watch the 3D version either way.
