We have already received more pre-orders for this than Abigail ever did so yes, I think it will be a decent hit. And no, most people here don't even know what 127 hours is.
It's hard to predict what will sell well and what will not. I thought T1000 (iconic character, loads of accessories, enough to make two figure) will sell well but it didn't. I thought Black Widow (bare bones, weird breast issues, limited posing option) will sell badly but it didn't.
Those on the fence might want to jump on this quick. Ultimately HT makes these figures based on the amount you guys PO. If not a lot of people PO, then they will be less made.
I dare say Superman will probably end up like t1000 because every other person seem to be ordering at least three.
