It's coming this Summer. Not in 1.18 but most likely in 1.19.

They are already working on it. Then they'll calculate how much it'll cost to implement it. Then they'll prepare and implement it.

The costs need to be calculated regardless.

Some of the stuff on that list is less likely to be implemented however. They'll probably come to a conclusion on the jumping and AH systems, but we won't see them before Fall.

It's better to expect otherwise, I guess. That way you can only be pleasantly surprised.
