I cant imagine them axing it just yet. The game still rolls in the dosh, and there is no guarantee after them axing it the players would just move to another of their hosted games and drop their money there.
I for one would not just migrate to Kamihime or whatever. I got my DMM account rolling and in a very solid state both lvl and power wise so for me it would be one less chore to do every day.

But again, the game does still bring in the cash, heck since they introduced the daily deals I guess the amount must have doubled. People who before just bought all sorts of Step Up gacha,Ticket gachas and whatnot also buy all sorts of the daily deals, so, while we dont know the numbers I doubt their cash flow decreased. Rather I woudl assume it increased rather nicely.
So I dont think we need to read to deep into this.

And if they really are that retarded sink this ship and hope people will just keep giving them money after migrating to other games... well then yes, they are retarded. People are not paying them because they wanna pay them. They pay because they buy stuff in the game they are enjoying, and if the game is no longer existing, and they dont play any other, up till this point from those that are offered, I dont see them just going "meh, I didnt play any of this shit up till now, but hey gotta keep em milking me, so better start one of these to give them my dosh right now".
So yeah, my 2 cents :P
