The more I think about it, the more I'd love to see a 4.5 upgrade for a reasonable price. They have promised so much, and we are all expecting it, and not only that, we expect 0 bugs, this would be an easy way to split out what is easy and what takes a little longer. As long as they give the 4.5 upgrade guys a slightly better deal on 5.0 it should be no major complaints. I did the same thing on SMV Essentials, the package was just getting so big and hard to finish I broke it uo in two, when the first came out it was already called SMV Essentials I, as I knew there would be a II! I haven't done any programing in a long time, but all proper modern programing is done in modules, assuming they are using the same language (I'd guess C++) it isn't that hard to move a working module to another program, especially if they were done by the same guys in the same style. However, if they are changing languages too all bets are off!
