I don't think it's time to doom and gloom yet. Tickets are still selling like hotcakes. PPVs have been massive. WrestleMania 40 is going to be huge. Etc. Plus, they did get an increase in revenue from moving to USA in this deal but I agree it might be a "at what cost?"
There's some things to be concerned about. Not necessarily Vince but I would hate to see Triple H leave. I don't really trust anyone else under that umbrella.
We knew roster cuts would come and so far there's nothing egregious.
I think in the long run moving from FOX to USA will devalue the SD! brand and I think that's part of the reason why the stock went down after the announcement but there were other factors at play too.
But again, it's way too early to be concerned. The recent RAW ratings though have been abysmal. That show has fallen off a cliff in terms of general interest.
