Asus p7p55D Pro or -E pro or -E deluxe

[lfforte]

hi. Can't decide. I'd like to get the motherboard with USB3 and SATA3 but how long before those become mainstream?? Right now I have no use for these.
What does the the p7p55D-E deluxe offer over the -E pro? I don't want to pay fpr spmething I dont need. I'm not really interested on overclocking. Which board should I go for?
