No. sub numbers will never be released and no the game is not dying the MMO hopers, trolls, and "Why is this not Skyrim 2!" players have left so its evened out. Games not dying.
I think that once they get the PVP lag and crash issues fixed that they will open up additional campaigns. I think they want at least one max capacity campaign.
One guy makes a forum post claiming there are 1.2 million players with 0 proof based on unreliable unconfirmed data from a company nobody has ever heard of an now we're going to be hearing this for months. On each post about the state of the game there's going to be one guy saying:
"Yeah, huh, I heard the game had 1.2 millions players, it was on forums a couple of months back".
I bet by then the post from the website will have been deleted just as the one that claimed the game had 750k subscribers witthout any proof what so ever.
