Don't forget that in Gamepark's case, the original product was essentially squashed by Nintendo. Even after they fragmented, both sides still couldn't produce enough interest due to Nintendo's previous interference. This time, it's an upstart against all three... if all three bare fangs, it's gonna be bloody obvious that they all have something to lose.
Quite honestly, I hate wireless controllers. My 360 has wired controllers on purpose. Is this thing HDMI-only? That'd be dumb... not everyone has an HDMI-capable set yet... we're lucky we have one here (it was free). Aside from those details, I could see myself coding something for this... if it actually comes out. I was kinda psyched for OpenPandora, but that thing's been a trainwreck over the years and I lost all interest in it.
