Now that I've been wanting to buy, it seems like all good deals have evaporated. I finally decided on the KDL60EX720, but would be willing to get the NX (I would rather have the semi-matte screen). There hasn't been any steals on 60" that I've seen. And no, I don't live near a Frys. The way people bring it up, you would thing that there was one in every state, not just a couple.
I'm moving back to Cali in July, but all the 2011s would be gone by then, and I know I wouldn't be able to pick up a 60" tv all by my lonesome.
My eyes have been peeled, but I don't think there is going to be any President's Day specific super steals. There are a couple of sites with so called sales, but the best I've seen is $15 off. Tigerdirect is a chancy online shop, but they seem to have the most good deals weekly. My tv hasn't come up for super clearance yet.
It's the year end, so you can either wait your time for the prices to steadily fall or stalk a few price forums like here and slickdeals, for the next deal.
Btw, $1600 for the 6000 is a bit pricey.
