As usual, DPReview.com is the first to break the story on the new Canon EOS 30D being released at PMA. It's basically an updated 20D with the exact same CMOS sensor -- the only changes are a slightly larger LCD, slight modification of the body (to make it feel closer to the 5D), and ... (drum roll please) .... spot metering.
Price looks like it'll be around $1300. I'm only slightly excited about this -- the mods are so small that they should have just called it the 20D Mark II and not get us all confused with the much older EOS D30.
A good sign that DSLRs are approaching maturity of sorts. The megapixel myth was a welcome way to differentiate, even though there was nothing really different about the machine. Film bodies' last frontier was fancy AF and metering modes, but they will hardly excite anyone anymore (and did they ever anyway?).
Only thing I can think of is in-camera IS, like K-M did, although to retro fit that on Canon or Nikon bodies may be difficult.
