I haven't heard anything, but I think they're just going to continue making small changes over time.
Just to catalogue enhancements in recent years: It started with the scoreboard upgrade, then they renovated the clubs and suites, they renovated the goal bar into The Lofts, and added the Studio Suites last season. They also added video monitors to the concession stands in the last few years, and added video boards in certain parts of the concourse (like behind section 101). And they renovated player areas when they moved the locker room to the other side of the building. Oh and they made the empty space behind section 225 a hospitality area although I haven't seen it up close and they don't seem to advertise it. I think it's intended for groups that buy a lot of seats in that section.
This season they've added the Prudential Lounge, upgraded the M Lounge (not sure what this entailed though), and added the Foundry Bar on the concourse. They also claim to have added 5G cell service and WiFi, though I haven't heard anyone mention it yet.
In terms of things that need upgrading:
- I can't see the restaurant needing much of an upgrade any time soon as it's nice and not outdated.
- I think most agree they need new seats, because the current ones are stained after 16 years of spills and people stepping on them.
- The bathrooms could absolutely use a renovation. I won't even list all the issues, but damn.
- It would be nice if they would finish the empty void next to section 209. Seems like it never makes it into the budget but it's been "unfinished" since 2007.
- I'd love to see them do something more with the space in between the concession stands and the big Mulberry Street windows on the upper concourse. They seem to use this for small season ticket events. It used to have a concession stand in there. My wish would be for them to make it a season ticket lounge with nice food/drink options for purchase.
I'm not an architect, but when I interned for the team in 2010, I would wonder around it a lot and I always got the impression that there was a lot of wasted space. There are random rooms in various places where the font office would just store stuff because it couldn't serve any other purpose. It's like they focused solely on making sure they could fit an arena, practice rink, and front office on the land, and everything else was an afterthought. I would love to see what a major renovation could look like, but with all the other recent upgrades, I can't see the ownership being interested in that for quite some time.
