Well, let's be real.
What was/is the reason for the delay? = dev's need more time.
Now we can think in two different ways:
1.- ZEMI realy try to do something good for the game, and we should respect it. At least till the day we will finally see it.
2.- "Devs need more time".. this could be an important sign: ZEMI goes bankrupt. I know it sounds weird, but it could be true. Just imagine, they closed Erebus, their main MMO 4S went from hundreds of thousands to max some thousand. And just imagine, P4 have every week also thousands of players! - this means they lost nearly their full range of customers.
Less money = less devs?, maybe~~~ (just for an example, Korea closed his 4S service, also other offical servers go down)
In fact, 2017 will be the final year, the pservers evolve now faster than the offical servers. The question isn't anymore "will they go down", its now a question of time. And LittleJoke is right, its atm just 2 months delay, to say ~8 months is not fair. It is normal to need months to develop/prepare a new patch for a MMO.
The new patch will be something we can't imagine at all. Sure, most users will say things like maps, skins, final release of 68PvP, LvCap, mounts etc.
We have to think outside the box, client improvement and again changes of the whole game concept (example Gor) could be the final patch.
I'm sure that ZEMI knows about their own status, just remind their facebook post where they asked for support to stop pservers. They aren't stupid, but helpless.
