Ah, you've just got to love the FCC and the way their public disclosure process ruins the secrets of many a company. Interestingly enough I've been told (so this could be false) that there's some sort of check-box the company can select when submitting their product to have it NOT appear on the public site...yet no one seems to do it. Apparently some things have been withheld though.
At any rate, these drawings confirm what we already know: there's a 4 GB and 8 GB Flash-based Zune coming from Microsoft. We were all about 90% sure, but we now know that the devices will also have WiFi built-in (coming from a Marvel 88W8686 chipset) - so it looks like the social is coming to these new Zunes as well. The question is, will the WiFi on these new Zunes do anything more than the last Zunes? I sure hope so, or these products are going to be hammered on as heavily as the last generation.
