Korg have announced the Volca FM MKII - which doubles the voice count to 6, adds velocity (over MIDI), adds a shimmering Reverb - perhaps from the Minilogue XD/NTS-1 family?
The 6 operator FM synth is also compatible with original DX voices over SYSEX (system exclusive) which makes it a great way to access thousands of free DX patches.
There's also a TRS MIDI out meaning the on board 16 step sequencer - with new pattern chaining, can now drive external gear too.
Available mid May, price TBC
