(Full disclosure: I'm invested in a Tron pro) but seriously in the current climate of pending oversaturation/too much competition...really? TronVE would be standing still/microwaving while you're the big bully on the block with (in some instances) 10 or more times the infrastructure/employees...while JJP grows more entrenched with new titles, Deeproot gets going with new titles, Spooky keeps going with new titles inc. Danesi #2, Chicago Gaming releases their highly successful remakes...these little guys are growing and soon will be 20% 30% the size of Stern and Stern will start to feel it as a finite pie gets divided.
If I were Stern, I would keep pushing forward as we move towards market saturation. New titles, stay creative and relevant and get new stuff to operators (not selling a couple hundred Trons to pinheads). And try to keep market dominance. IMO 2019 isn't the time for vault editions.
I say this was some ambivalence, as I actually love quite a bit (and own) JJP and Spooky machines...but this makes more sense for Stern.
...and release TronVE maybe in 2023 or so when the storm is over and the market is depleted again.
Just my .02
