There's been a lot of innovation in music tech with synths like the MicroFreak.

Korg have made a series of original synths (and VSTs) that are nods to old tech with a lot of updated features.

The VST market in general is a bubbling mix of clonery and originality.

The reissues and clones are for people who want a specific vintage sound but can't afford the insane prices of vintage originals.
