Thing is.
2 Months of development won't be 2 worths of content, more like 1.5 month.
When you are working for 1 month then you have a sense of Rush and Deadline stress so you will work to the fullest.
When you take 2 months for it then you have a sense of ..."ah well, we got time enough" And that leads to the "oh no, we did not do what we wanted so we have to SpeedRush a lot of things" and that leads to less content and more bugs.
And that's only getting worse with the more time you take...
And i hope that he is going to keep his worth to make the coming update(s) about the old characters, and start to flesh them out or even finish them.
But knowing Sunset and the team...Would be probably handfull scenes for old characters and a new char that's going to be ignored after that.
(Don't mean it all that negative).
But it's just that he needs to start to finish what he put on his plate instead of coming for second and third helpings while the plate is still 90% full.
