I would say that 2.9 is almost ready; just doing some testing and have one more thing to do.
RP3 is going to take a little longer - I want to take what I've done on ViperAlley with the concept of Manufacturers/Dealers and Products which can be crosslinked and make that the next stage of development. I don't know how long it will take, but I would say 1-2 months with a BETA starting before that.
That's why I went for the 2.9 release, I know we have people who are anxious for the vB3 Enhanced features and I think this incremental release with some optomizations and bug fixes is just what we need to keep the interest going.
Please do not PM me for support or sales questions. Thank you for your understanding.
