Not sure how many consecutive players can be on the servers at a given time, but seeing as both servers have significant queues (Around 3000+ combined), I figured I'd look into how that compares to other Super Hero MMOs.
According to Steam Charts, Champions Online is averaging close to 300 players a month getting into the game via Steam. DC Universe Online is fairing a bit better, averaging close to 900 players a month.
There are 3000 people lined up, waiting patiently to play a shuttered 6+ year old game.
I definitely hope certain parties are paying attention to those numbers.
