Well personally I wish they would replace the seats just to give everyone more room. I’d much rather a little more width and the stadium only fit 40k then 50k because realistically 90% of the time we are at the 25k mark Not only would it be more comfortable it would make the stadium feel more full.
that's happening. stadium hasn't fit 50K for a few years now because they've been removing seating to widen the concourses etc.
There's lots of speculation on what they're renovating but it's almost certain they're re-orienting the seats to face home plate and putting in more modern seats which are wider.
