5:1 sounds about right.
Everything about Sony's PS3 motion controller seems to be half-assed (just like their other attempt with the Sixaxis). So far we've had a seemingly put together the day before E3 presentation, a promised release window that was obviously pulled out of their asses, less third party support than Natal, and virtually no attempt to get the audience that should be caring about this to actually even be aware of it. This is a disaster in the making and I'm calling it just like I called it with the PSP Go.
