well I have a 3 year old - basic delta that will happily print at 150mm/s.

So nothing really new there.

They've improved all the relevant bits: linear rails, better arm design, decent hotend and a good extruder.

You'll need to optimise the bowden tube and feed path yourself. But that's just something delta manufacturers just seem to have no clue about anyway.
Actually I honestly don't think I've ever seen a bowden tube on a stock 3d printer that has ever been in the right place or the right length.

But yep definitely looks like a very good delta at a decent price.
A bit more height would have been nice - but otherwise, very nice looking machine.

I also like that they've used silent stepprs for all 4 motors. Most skip the one on the extruder. And delta extruder motors can run pretty fast when the machine's in full flow.
