So I ordered my iMac august 7th and decided I wanted the wireless keyboard. I was willing to wait for the keyboard but was hoping it wouldn't actually be a 5 week delay. I decided last night that I just couldn't wait any longer. I was willing to pay the $50 dollar difference to get a wired keyboard with the iMac and then have them send me the wireless when available. So I called apple this morning to change my order and they waived the $50 dollar difference! So I got the wired and wireless keyboard and only had to pay the $30 dollar upgrade. Just thought this might be useful information to anyone else who ordered an iMac and is still holding out for a wireless keyboard. PS - I have read macrumors EVERYDAY for years and this is my very first mac.
