The interesting thing is that the collector's edition is released 8 days early to allow for a headstart. They could sell them at the same time, with only the collector's edition working initially. Likely scenario is that if you were able to get ahold of the regular edition and installed it, it would probably still function. So I suspect it will work, but we'll find out in a month right?
