Past Velious??

[Baler]

No. Blue & Red will never go beyond Velious. They are era based servers.
There is talk of another server. No hard facts yet but that may be where the custom content goes. Blue and Red will act as museums of a glorious time that has passed in which p99 staff have recreated through hard work and information contributions via the community.

There is probably a hundred threads you could searched the forums for who have asked the same question you have.
