Up to date list of GaN Class D Amplifiers?

Thanks George

I'm hoping to hear one soon.

There are several coming out ,but the prices are just nuts,the GAN circuits are not that expense to command say from $10 k to $20 k+ 
markup as I have stated many times being involved with R&D  ,my uncle being a Audio engineer, and markup is at least 4x or more which the parts cost.
when . Just like when new computer technologies come out it is way over priced 
give it a few years much  more reasonable . Let’s see in 3-4 years.

See Voyager GaN amp, to be released very soon MSRP $2500!

I will be comparing it soon to my ,much loved EVS1200 class D from Ric Schultz ~ $2400

Anyone heard one?
Is it really a game changer?
Is GaN likely to reach the mass market?

Yes, maybe and yes.
GaNFETs are pretty cheap nowadays so anyone can design a circuit using them inexpensively.

But MOSFETs aren't out of the game yet; some of the newer ones are easily able to switch at the same speeds as GaNFETs currently in use.
