I know you said this is a re-write, but are any of the fundamentals changing? For example will you take the opportunity on X-Cart v5 to implement a proper DB abstraction layer and support multiple databases? (it has always been a pet peeve of mine that I must run MySQL for a single app on my box, when everything else uses PostgreSQL, and I have PgSQL tuned to be allowed to consume a lot of resources if it wants). Or is the backend stuff (supported databases, and the rest) staying the same and the changes mostly focusing on the user-visible stuff?
