Some of My Ideas :)

If you mean buyable items with objects like a tree and your own personalised house then it'd probably won't be done because theres a object limit and if its buyable with in-game money then its pretty pointless because it'll probably lag the server because everyone will buy their own house and get their own objects, but maybe owning a personal car wouldn't be too bad.

Permanent gangs is possible but I don't think they're doing this in 2.9 supposedly they're doing it in 3.0 but thats gonna be like in 100 years.

Finally, making everything VIP will just be dumb because then the server will be even worse as it is, since all the more fun features will only be for VIP and not everyone will be able to donate.
