That camera actually sounds pretty exciting.
As a Sony shooter, I followed the recent announcement of the Sony A58-- which also appears to be offering a significant sensor improvement. Unfortunately.... I think Sony is tinkering with their product levels..... There were rumors they were going to announce the A38, and then at the last second... lo and behold the A58 -- with many features taking a step back from the A57. So I get the sense that the A58 is their new entry-level, and is really replacing the A37.
If I wasn't invested in Minolta/Sony... The D7100 would be very tempting. I'll be interested in the eventual A78, which rumor suggest may use the same sensor as the D7100. Due to the translucent mirror though, it loses about a half-stop of noise performance.
