The Epson is almost never available under $2,599 as that's the manufacturer's fixed minimum price, but Amazon just dropped their Epson 5020UBs to $2,469.20 -- and on this page there's a link for a $2,449.22 seller as well:
I'm starting construction on a new house and will be having a dedicated theater in it. The 5020UB is on my short list and I've been keeping an eye on it on Amazon and I saw that price drop over the weekend. Well it went back up this afternoon. But perhaps that mines the price could continue to move over the next few months.
