Honestly, I don't think so (just my personal estimation). As its name reveals, it's a "Pro" titler. The normal text features should be enough for most Movie Studio users...
You never really know for sure. I'm quite surprised at some of the high-end features that have made their way down to the Studio version. The only way to know is to wait for future versions. SONY certainly isn't going to tell you, and any non-SONY people who know can't tell you.
Well, Sony Vegas Movie Studio seems to be very popular with users of HDV cameras like the HV20 etc so you never know. Even a non-pro version of the titler would be a very nice addition.
