Great Wireless MIDI devices as EWI MIDI extension, but no longer available!!!

I have used a Guitar Wing by Livid Instruments , Hothand USB wireless midi controller by Source Audio along with my EWI5000(and WX5) to add more midi controls over various sound modules and VST instruments. These are great tools with motion sensing accelerometer . But they are no longer on production unfortunately!!!
