I can't find the article I read on N4G but it was something along the lines of Sony releasing SW backward compatibility in Japan on the 40 gig with the next major firmware release. I find it extraordinarily hard to believe but apparently there are many that believe it is coming because I see posts all over the place about people referencing how SW backward compatibility this fall will be the ultimate win.
I suspect it is just a fanboy rumor and has no basis in reality but thought I'd ask none the less.
