Scott -
From my perspective...I've made every upgrade beginning at CWPA 8. And for the last eight years (part-time for the five years prior to that) I have made my living with Cakewalk products. For me, I buy products (not just software) after researching then deciding what features will work for me and which won't. If there are more negative features than positive, I pass. If I go ahead with the purchase, I embrace those features that work and stay away from those that don't. I have been very successful using this strategy.
Now, I'm assuming you haven't purchased X2 yet. I assume this because, as a professional, I know you've done your homework. If you see that the lack of VST3 as a deal breaker for you, what choice do you have but to move to another platform? I totally understand the expense and time but if the product is going to stop you in your tracks, I don't see that you have any other choice. The only pitfall here, no DAW is ever going to do 100% exactly what every person is going to need.
I have seen these same exact threads occur year after year, it's just different issues. And for the most part, those mostly greatly stressed out over the non-implementaion de jour are still around when the next version rolls around.
All in all, X2 am what it am. The back and forth debate regarding the inclusion or lack of VST3 is a moot point. It's not in X2 and won't be at this time. Feel free to submit Feature Requests as some of us have done for two years for something as seemingly simple as color customization.
So good luck whichever direction you decide to pursue.
And FWIW, I do understand I won't change your mind.
