Your questions yesterday and today are very RED-specific. If you need an editor that is able to work with RED cameras perfectly, you might want to get FCS. Apple and RED are working together, and that's the best known combo. And even if Sony support RED in the future, don't expect that support to be in the consumer Platinum version. Either way, you will have to upgrade.
I also wonder why a question like this is asked when it's a lot faster and easier to go into Vegas' properties screen and try typing in 120 for the frame rate. You'll find out that Vegas' limit is 100 (at least for the Pro version, the studio version might be lower).
