I would not expect it until at least 6 months from now, probably more. V5 came out less than a year ago and there is usually 1 year and a half between versions if not more.
Hey Guys? Just flown in from Beetlejuice . .. you still on V6?
We just primed up our Trigithon ZooZapper and have V2Giga playing your WHOLE World - in virtual space! Neat eh? We got Nested Planets and Z-D Planars and some bald headed geek called Spotskim running riot with the new Drogo-Fly-Eyed HEadset .. . Tera Kooollll...
. . gotta zap .. been here far too long . .. oh yeah . . . . sorry, gotta zap .. been here far too long . ..
The next version of Vegas, I would suspect is an update that works with HDV. Is Sony going to throw other features into that release like when 4.0b added 24p support, I have no idea. But I would think there would be an update of Vegas 5 shortly and then Vegas 6 halfway through next year.
Let's See? I seem to remember that the best and most reliable leaks of the arrival dates and features of Vegas 4 and 5 - were found first at the SCVUG! Need I say More?
I already saw a demo of 6.0. Unfortunately, I cannot recall much about the demo since I saw it during a day dream. I was experimenting with some new time travel mechanism.
