For sure... "sell out" is just marketing hype nowadays.
The Yankees have forever changed the appearance of their home games by kicking fans out from behind home plate during the regular season (by the creation of the luxury ticket... $200+ for a r e g u l a r season ballgame), limiting access to those sections, creation of the sports bars behind home plate and center field which now allow fans to sit inside all game.
I doubt there will be more than a handful of regular season games with a "feel" of a sellout, truly sold out seats.
Only the sports broadcasters and a few millionaires are happy with the new stadium. For me, it feels... well, I can't describe how it feels. Different in some way. Hygienic somehow.
I'm also already sick of the food venues. Seems fans are willing to stand in line for half a game to get food (??!??!) What's up with that? I mean, yeah it's nice to have something other than hot dogs, but when a food line is held up due to beer foaming (and the resultant need to slowly fill a giant cup of brew.. times 6 because a guy is getting brews for his buddies) or because they introduced 25 options increasing the serve-time 10fold, it's not worth it to me. This goes for new stadiums I've been at with the sole exception of my one visit to the nationals stadium (back when they stunk.. NO ONE WAS THERE
) -> phillies, yanks. Camden Yards, if I recall, is a bit better, but while new-er... it's not brand new. It has those open food areas down below that don't seem too bad to me.
