I've always thought that Wembley looks great on TV. Especially once the light fades. It helped this year that they seemed to add a little to their production. I'd happily watch the Sting/Darby entrance from the first All In and Ospreay/Omega from this year, and the crowd being half the size means nothing to me. Having Wembley every other year can work. Where to go in those alternate years can be challenging. MLS stadiums in LA or NY areas? Northwestern just opened their new football stadium this season, that gives the Chicago area a modern 30k stadium that AEW should be able to make look good.
On the TV front. The standalone Rampages and launch of Collision didn't help. Spread things too thin, burns out crowds with double tapings. The expanded PPV schedule minimising the importance of TV has been another dent. Went from a 4-6k expectation for a Dynamite to grinding out 2-3k unless they are in major markets. It has been that way for years. There have been changes in that time thankfully as they faced the goldilocks problem. The extremes of Cavernous arenas and tiny residencies have been squeezed out of the rotation to where they are not as noticeable. Starting to go international a little more often. The golf arena and Jericho cruise giving some novelty.
