Well, it looks like that CECHG01 model PlayStation 3 wasn't the only one that the FCC got to spend a bit of time with recently, with the hereto unheard of CECHH01 model now also finding its way into a couple of more recent filings with the commission. While we can't say for sure what's what, that model number is certainly more than a tad similar to the recently revealed 40GB CECHH00 model announced for Japan, which would seem to suggest that this one can't be all that different.

Additionally, from what little info we could glean online (see link above), it appears that this particular model packs a "new board" and, most likely, two USB ports instead of the usual four. More on this as we get it.
