Gentlemen, I'm sorry to say that, but I doubt, that 777/1CGS will ever come back to this game. I gave up all my hope.
They are collecting player data via the master server, so I'm pretty sure they have very reliable numbers of active players. With those figures the can calculate a quite exact return on invest. If there's good money to make, I'm sure they would have come back and add more content to collect this money, but they didn't. Guess why. It seems that they skipped any effort into this game except the maintenance of the master server. Even a pending skin pack doesn't find it's way into the game. And if you have a look at the number of players online on MP servers you'll surely notice that there are less almost every day. The only thing we can expect from 777/1CGS is to milk that cow until it's totally empty or in other words: You will see a Big-Sale every 1-2 month until they sell the game for 5$ on a regular basis and after a while they will skip this as well, because at a certain time the cost of running the master server will be more than the get out of it.
Rise of Flight is dying a long and slow death and it is already in the middle of this process.
So dream on, but to be honest, it ill remain a dream.
