No offence intended…
But these guys are taking the MidiFighter to the next level…
STarrlabs AirPad
Wireless, 4x4 pad, x/y touch pad and knobs!
Those aren’t really arcade buttons… Plus their overpriced… No offense taken.
The VCI-100 never had “real arcade buttons” initially either, i.e. things can be modded. But if this had real arcade buttons and the price more reasonable then it would put up a fair challenge to the MidiFighter…
16 arcade button, X/Y pad, knobs, cursos…all that’d be missing is a few faders.
Oddly, I put a post in the controller section a few weeks ago about building a custom MidiFighter with an X/Y pad attached on one side (custom made from a Nintendo DS screen possibly) and knobs and faders the other side.
I’m obviously a visionary! 
seen the guitar idea before but was made better.
also wouldnt say the controller makes any advances
Plus, ever since I saw this:
Wireless Controller
I’ve thought about how cool it would be to have the freedom of a wireless controller.
