UK recommended retail price is £2500 (going off preorder prices), which is around $4000USD.
I've been weighing up the idea of a better SLT for some time, as I started my foray into SLRs with an entry-level alpha 230, and now have a few minolta lenses in my small collection (and a job to pay for better kit :D). I do a bit of aircraft photography however, and my major concern with the A77 was that using a fast fps means that the displays black out whilst the camera is taking the images - for a fast jet that could mean that I cannot see the aircraft whilst panning across the sky taking a burst. I don't know if this is actually an issue (maybe a A77 user can correct me- I'm going off trailing the camera in the shop) or if it IS an issue which may be resolved in the A99.
I'll await the full review - but if anyone has any comment, I'd be interested to hear it.
