They needed 2k fans to keep sport viable the MEN, which they didn't get in the main so that is why it stopped being there, it was never a big earner.Looks like their idea of an upgrade is to add more areas to the arena which people can't afford?
Interesting to see which arena gets the top acts going forward. The Co-op Live is clearly built more with music in mind whereas the MEN is and always will be a sports arena that hosts concerts. The difference between the MEN and all of those similar arenas in America is that these all have sports tenants(or multiple) that ensure it is used for 3 or 4 nights a week before you consider music events. The MEN hasn't had that for 20 years and will now have a direct competitor for boxing events too because of the flexibility of the Co-op.
It will come done to who can earn the act the most money, so it won't help ticket prices. The MEN has a much better location but that is about it. The COOP going for 180 days' worth of events a year could be aiming to wipe out the MEN, however the latter downsizes for some events and may start competing more with the Apollo etc and get smaller acts if forced.
