I've been looking forward to a Sony DSLR with the interval shooting option. The Konica Minolta 7D was ahead of it's time, with the interval shooting option, but the batteries couldn't power the camera for long shoots. I wish I had bought an AC adapter. Sony has not put that option into any DSLR. I know the A700 has a firmware update for interval shooting, but the A700 needs to be teathered to a computer. The new Alpha SLTs don't have teathering and as far as I know interval shooting is not an in camera option. You can buy third party hardware to do interval and remote shooting.

This device is limited to 99 frames and costs $99.95.
I would find it handy to have interval shooting as an incamera option in a Sony SLT, without the in convenience of teathering. I have the AC adapter for long shoots, but I may need to purchase the Vello hardware.
