No, I don't. I think all money spent on developing it should be spent on ACTUAL improvements. For instance, it would be cool if Vegas didn't still crash 20 times more often than Premiere Pro CC.
Well, the big changes in Premiere when they went "Pro", made me change to Vegas.
So, unless they want to roll a dice without benefits, keep the same.
as mentioned, fix the bugs, implement more functions, make customers happy. the GUI of vegas is already clean, basic, and fast. most likely any changes will not enhance anything,
just look at the the B&W icons. only complaints. how many people *actually* think that was a good change?
if they change, most likely will be to "make different" than to make better for the real customers.
