To add a different viewpoint to this discussion (as I have been looking for a cheap new copy of the stand alone game for the past 6 months and have missed clearance sales), this game is practically non-existant on any of the major websites, with the final one being Amazon (albeit this is a big one).
While it's true there is a spike now on Ebay due to the holidays, I would predict the new copy value (standalone game) to hold at least to $20 (if not more) for some time. Right there alone, this would mean you are roughly getting the limited edition gold CC pro for only ~$15-16 (accounting for tax on the game), which I think is a good deal if you are a collector.
Yes, there may still be some clearance LE bundles left in the wild at places like Big Lots / TRU / Walmart, but for most of the US, online will be their only option, and they will look to the only websites left that have them (Amazon and Ebay) for their value.
If I were you, I would buy two copies, sell one sealed for around $50-65 (should be able to eventually), and then keep / sell the extra gold controller (which by itself should sell for around $15-20 easy).
