Question-Advise: I started with a Minolta HTSI 35mm SLR. I am now using a Minolta 7d. I am looking for a second DSLR and was considering Sony Alpha 100 so that I can continue to use the lenses that I have and am happy with. I have done some research. I understand that upgrades are comming up both by the end of 2007(for the Prosumer) and also March of 08 (for the pro camera). I am considering just waiting for March of '08. Just looking for some additional input on my consideration.
