I think a major issue they're going to have is a lack of internationally known endorsers. They have no way of supporting anyone on a worldwide tour as there's no physical presence anywhere except the UK (and even then only in York) and a relatively small network of dealers in the US only. The few endorsers they still have, whilst decent players are basically unknown, or really only active in the UK.Then probably Tama, Yamaha, and Pearl are not real either. Or you could argue that they build their own factories in China, while Premier just outsources from an existing factory.
The bottom line is, the factory still makes the drums according to the design and specs of Premier drums, so they aren't really less Premier IMHO. The new Genistas are actually more accurate reissues than, say, the ones made by their 2010's incarnation. This is unlike say Trixon, which just puts their badges on OEM drums without designing them at all.
The new Artists look like the former Chinese-built APK's and XPK's to me, and the Artist Heritages look exactly the same as the APK Heritages. There used to be a Keith Moon commemorative APK kit available in some countries. Solid kits, but I don't expect former Artist quality.
The new Elites, as a test run, are very attractive drums. In European countries they should have a competitive price, too. I wish they could introduce more sizes (tuna can anyone?), more classic finishes, and die-cast hoops (they could re-tool for the Genista so why not Elite?).
