I'll be honest - I haven't upgraded from Pro 12 at this point and am wondering whether it's really worth it, especially since DVD Architect hasn't needed a much, much needed and long overdue facelift. Even Vegas would do well with some interface changes that remove the traces of scroll bar awkwardness, but that we can handle. Not updating DVD Architect this go round? It's like episodes of Star Trek. Only the even numbered releases are worthwhile.
