The thing is, it's an at-least-partially closed design, the only way to get it to subscribe to the kickstarter, and it doesn't comply with the modern enhanced-Spectrum-graphics standard ULA Plus, because some of the team had an argument with some of the ULA Plus team.
The Chloe has been around for longer, it's 100% FOSS, and it runs on the €35 ZX UNO FPGA board.
They're both interesting but IMHO the Chloe is more interesting.
BTW, I have no connection with anyone involved in either bar talking to them on Twitter & FB. E&OE, as they say.
Still, this is good news. There are already enhanced games that use it, originally for emulators and later for machines upgraded with a physical ULA Plus chip...

... and now you'll be able to play them on actual hardware.
