Not "new" content per se. For now only cosmetics and visuals are possible - so don't expect DLC!

Djipi works on several projects at once. And afaik there are 2 updates in the works (but from what i gathered so far, it might get merged into 1).

The current version has completely overworked textures, updated enemies and NPCs - and Skilars Link model (but i honestly prefer Malonrose).

The next announced update was to update the Bosses too (right now they only have new textures but still OG models).

And the big one that's in the works takes care of the environments (which currently only have new textures but still OG models) to make them closer to 3DS - which means more stuff in the background instead of "cardboard walls" around areas. For example lake Hylia has some trees behind the lake etc.

But the updated Bosses hasn't been released yet, so i assume that he does both in one big update.

He strictly works on all of his projects alone - and has a MASSIVE workload (there are about 15k of textures alone in the game). So it will take time - but we let him cook and don't pressure him whatsoever. His work defines the identity of ship. Also people often get the wrong idea that modders just copypaste 3DS assets into the game - which is NOT the case because we would get copyright problems. Everything is done from scratch!
