[mention]zedsouth[/mention], you are simply reading what you want to read.
It was stated more than enough that nobody is abandoning this game, not Shane nor any of the staffs. The new game is Shane's new project and has as also stated a few times NOTHING to do with PRO at all. The game itself will survive as long as PRO can pay the servers of the donations.
The yellow server was necessary duo to too many players back in Summer 2016.
The content for PRO doesn't stop, Sinnoh is being worked on and new stuff will come. Arnie just recently came back as a Staff and since then he brought us multiple new bosses (more to follow), the Johto Dogs, a new legendary, a ton of new TM moves and so forth. Shane had almost nothing to do with it.
The new game from Shane, is something else, something new and yes players will switch BUT this won't happen for another year.
