I have been playing Dungeons & Dragons Online since 2006, and Dungeons & Dragons: Neverwinter is looming closer. Given this fact, and the differences between these MMOs, I would say another concurrent Star Trek based MMO would likewise be Star Trek, yet very unlike STO.
With luck, it will be given to a new development team and publisher, who would give the IP the justice it deserves.
I would have no issues with this game staying on and people who have invested time and money into this game being allowed to still play, however that would probably only happen if PW made STO 2, so you would have a situation like Eq 1 and 2.
If not, it would more than likely spell the end of this rubbish, which I would also have no issues with, even if you have spent time and money on it, as you don't own this game like a single player game and any MMo can closed own at any time. Bad luck is all.
The question though would be what would "you" like STO 2 to be. This game but with more content and more factions? If so, then they might as well not make one and just make more content and more factions and not just dil sinks or grinds . Nah, Not me. Not STO with a few more bells and whistles.
I'm still not sure what I would want from an STO 2 I just know I don't want it to be anything like STO, but I do know I would want the chance to talk first and not Pew Pew everything...

Look at WoW, they've managed to implement new DX11 rendering API, however, it is still hampered by its texture support and quality and overall polygon count. Still, I think the Cryptic engine this game is running on is way more flexible than the WoW engine was, so in time, I think they could implement new DX11 specific features and affects. This game already has a Beta DX11 rendering API, it just needs the assets behind it to fully take advantage of all the special rendering effects supported under DX11. In other words, there is room to grow, a lot of room to grow, and if they have the resources for it, just like we saw in WoW, things will evolve in this engine as well.

What happens if one day STO 2 comes out? Will I lose everything or could there be perks for my new character in the new game depending on the progression of my old STO 1 character?
It was difficult enough to get this one released, much less a sequel. I'm not saying it's impossible of course, but it is extremely unlikely in today's economic climate. Just look how many games failed between 2011 and 2012, either before or after release.
My guess is that STO will soldier on in various forms, until it's financially or technologically unfeasable for them to continue with it.
