There's nothing about the current stadium that sets itself apart from other venues. It's fine and much improved from the concrete monstrosity it was initially, but being "fine" with nothing to do in the immediate surrounding area isn't going to vault you up many rankings lists either. If they build a new stadium and learn nothing from their (JR) past mistakes then sure, it won't make a difference. I'd have to imagine that the new leadership will not be following in the footsteps of the old regime so I'd bet they're focused on what the best location for a new venue would be plus what would optimize the pre/post and in-game experience.
