i voted here to stay, it really doesn't make any sense to kill it off until it's replaced with 'super high dynamic range'. i mean it's not a feature that will get old, it's just evolution of video reproduction, like increasing pixels. even if it's not needed, its not something that will make video worse for a large segment of the population like 3D did. but realistically i will NOT be the one making this decision.
i expect that HDR will either be the standard or dead and gone for a few years before i buy into it. the fact is, i'm just nowhere near an 'upgrade cycle' with my gear right now, and i see no reason to jump into anything new at the moment. even with 'improved standards' there are some drawbacks, so it's like 3 steps forward, 2 steps back(or maybe 2 forward, 3 back, don't know yet), and i'm happy with what i have now(haven't been able to say that for a long time!)
