Assuming the new arena is on the Myriad/Cox Convention/Prairie Surf site given the size and location, the Myriad will have lasted approximately 25 years as next door neighbor to Paycom Center.

Paycom Center from a facility standpoint is in much better shape as a modern arena for concerts and events compared to the shape of the Myriad was in 2002, other than the north side renovations and convention space that was added on with MAPS. Many of the concourses, restrooms, and common areas were still stuck in the 1970's.

It would be nice to see Paycom retrofitted into a nicer performing arts and convention venue, will the existing arena "go away"...someday, but my guess, not for at least another 20-25 years?
