Nikon D7000 Upgrade? Worth it to Buy D7000 Now?

I have the Nikon D50 and am planing to upgrade it soon. However, I've read that nikon will release more DSLRs before the year ends. Is it worth it to wait for the D7000 upgrade/replacement? Also, if I wait for an upgrade, will the price be much different than the current price of the D7000?

And that is the $64, 000 question…

The 7000 is a 2010 model… If your camera is about to die, buy a 7000. If not, be patient and wait another 2 or 3 months until the 7000 is replaced.

Based on Nikon's track record, the 7000 will probably be replaced in late August or September.
