It's literally been about almost a year since we have received an actual update that modified the game/engine without it being addon based. Anyone could make a Speedkart/Racing addon, considering the karts themselves were made by an addon maker. I was really suspecting an update this month or last moth, Blockland's rate of development is really slow, I understand its just one or two people working behind scenes but they will need to work harder if they want this game to get better and grow, user-base wise. Just because a game is Greenlit won't exactly guarantee it will dramatically increase the user base, it's not like people will buy anything just because its on Steam, the gameplay needs to be good. Look at the new game CubeWorld for example, it has very good gameplay and is packed with features, it's already very popular and the Alpha was just released a few days ago.
One thing Ive realized though is that Badspot has had to deal with idiot users (hackers) lately which may probably slow development rate down even more.
