1. The hardware is upgrading too rapidly.
Sell what you can and then fit it for the next sensor.
2. Buyers are in a hurry. (More than the various marketing depts. thought.)
Get the product out before the market place leaves you totally.Also .... The new Sony DSC-F828 for < $1200 no interchangable lens, but 8MP, Compact Flash, and a long zoom. Could hurt the low-end DSLRs if they can get it out soon enough before Christmas. Collin
