ahhhh...I wasn't the one that actually noticed it. A friend did and mentioned it to me so that's why I thought it was new. I knew I was have noticed it if was new this year.
In fairness, most of us haven't been in the stadium since...2019, I guess?
Anyway, it's clear the fake turf looks a lot better than the old astrotruf and it seems to be better for playing on. That said, we're still one of only 2 stadiums that use it (and The Trop is an all-time dumpster fire of a facility) and clearly players prefer grass so as better as it is, it's not grass.
As for the new jumbotron, it kinda feels like they just updated it? The image posted by Hazel Mae does look kinda wonky but it makes more sense when you look at the turf image above and realize it's really just replacing those pixel boards on either side. As long as they're using it that way, and not showing a single image (the way it is in that first image) I'm sure it'll be a nice enough improvement.
