Yeah, I'm not sure I caught those posts. . .it was a foregone conclusion once we knew the Avengers film had Thor in it, and HT generally makes better figures the 2nd time around. Having said that, my advice in the past has been to buy something when you are on the fence, just in case, and so you can enjoy a figure until the improved version gets released (at which point you can sell your older figure and use the funds to pay for the new one most of the time)
But if you really want the best high end Thor figure ever, and can wait a year and a half between releases or whatever, then why stop here? I'm sure the Thor 2 version will be even better. And the Avengers 2 version will be even better than that.
