As an answer to most of your questions, we should have the 2.3 chips within 1-1.5 weeks. We are however offering the 2.3b PRO upgrade from the 2.3B LITE for PREMODS that people are waiting for, so if you are waiting for a 2.3b lite premod, and want something fast.. you might consider buying the 2.3b PRO upgrade for 15 dollars which would make your console ship within 2-3 days.
We're also going to be offering the xenium premods shortly, and will also offer a XENIUM upgrade from the 2.3B lite premods, for those who want the ozxodus chip (which is in stock and shipping) and not have to wait..
