We've seen plenty of PlayStation motion control patents from Sony, some of them surprisingly similar to what we've actually observed of the as-yet-unnamed controller. This new one, however, gets a little odd. The basic structure seems familiar, but Sony's recently-filed patent application deals with add-ons in wild ways that not even the peripheral-happy folks at Nintendo have envisioned. Our favorite is probably the double-ender (Fig. 6B for those of you following along at home), which is probably the most assured recipe for a little brother's bloody nose to be run by the U.S. Patent & Trademark Office since the longstaff was invented. So, does this mean more cash to shell out for a "full" PS3 motion control experience? We can't imagine Sony being gung-ho about that strategy in the face of the (as yet) add-on free Project Natal, but we suppose we'll just have to wait and find out.
