Remember you're talking about the dude who pushed out one part after another for eight months, then delayed part 9 for a while, then went on a very long hiatus with part 10, but managed to put together a "Christmas special" in the meantime.
I would understand two installments of (actual/legacy) act 1 part 10, one for son, one for father, but this is getting drawn out and there's still nothing about (actual/legacy) act 2, let alone act 3, and remember that the first release of legacy act 1 part 10 was already over half a year ago.
Assuming he's just milking and plans to continue doing a quarter of a part every two months, then you can consider act 2 to have 40 releases and act 3 another 40 releases, one release per two months, so if he continues the same way, that's 13 years and 4 months to finish. Some people pay up mortgage in less time.
At least it's obvious why he offered those free memberships to people who supported him during his hiatus. It's not like they're worth anything substantial.
