Hopefully there won't be too much duplication. My understanding of the situation (from [link] ) was that Castle and ROL had reached agreement that the two branches would merge. So whoever is doing the merging must have access to the source for both versions. Right?!
I'd hope that Iyonix Select will represent the merged version.
Incidentally, TIB has an interesting quote from ROL regarding Iyonix Select.
