I really lack the motivation to keep close track of Proxxie nowadays.
His last update took 14-15 months or some such, for which he profusely apologized and promised to do better and get back to his previous schedule of 3 months (for the third time), yet this update is already something like 10-11 months in, and he's apparently been banning anyone who even asks about progress.
I see absolutely no reason to believe that he will ever get any better at this, but I unfortunately have faith that an update will come eventually, only that these updates will take longer and longer each time until he abandons the project or has a psychotic break.
You'll probably get 2-3 more updates to this rpg maker game over the next 5 years.
Whatever that means to you, it's the most likely story.
