Yeah, if you are going to buy one, don't sell it when the updates come out unless it is significantly better. The rumors point to the fact that Apple is likely just going to drop the new processor more or less in the same setup. So if you buy, wait until there significantly upgrade the rest of the guts, like with new graphics, motherboards, etc. Its not worth the hit you'll take for just a marginal increased in power. By the time you can fully take advantage of the 64-bit, you will want/need a new computer anyway. Whatever you do, good luck and enjoy your new computer, whenever you obtain it.
