I don't mean to be a killjoy but I'll be very surprised if we get a whole gamut of new moves with the vtrigger changes.
On one hand, it makes sense to give characters a couple of changes (ala SF3 with it's super art select) BUT those take time to add and can be difficult to balance.
Instead , as this IS capcom we're talking about , I think there's a high chance ALL we get is what they've shown - new Vtriggers. In this way despite the nifty looking new animations , they don't have to go back and tweak things extensively and rebalance the entire game around them so much. They just serve a single unique purpose that differs slightly from the way they worked before. Otherwise , vskill and CA behave the same way because of how SFV operates in general.
Someone above mentioned Chun having Kikosho as a new trigger and well, that's a single use big damage reaction attack. In other words you could consider it a defensive damage burst , sort of a back off attack. Just like it was in 4 really , if you're playing against a Chun and they have full trigger you have to be a little more careful with jumping in or you might get punished. Compared to the more offensive timer buff that gives you more hits , which is clearly a rush down assist. Does anything else really have to change there ? you basically choose Vtrigger based entirely on whether you want a defensive option or not.
Given SFV's structure (it's mostly rushdown friendly across the board) I actually wonder if ALL of the vtriggers will simply lead to a defensive option that doesnt' exist in the current system. Even that picture of Mika's where Nadeshiko has the chair , perhaps you can pop that one while under attack and it acts like a counter move like a tag in during a wrestling match.
It's all speculation for now but I've learned with Capcom and SFV in particular to hope for the best but expect the cheapest solution. This , in spite of season 2 going a route quite different from what I was expecting (you may recall I was sadly thinking they'd just throw in story mode models for all the new characters and they'd use animations recycled from the rest of the cast and character 6 would just be voilent ken)... I'm glad I was wrong there and I would love to be incorrect here too.
