We love a good non-mystery around here, and Microsoft's new Zunes are about as un-mysterious as they get. But we also love a good product refresh, and now that the cat's officially out of the bag we can really dig into the new Zunes, which definitely have a lot going for them. There's plenty to cover, so here's what you need to know.

Hard drive Zunes

It's called the Zune 80 and, shockingly enough, it has 80GB of storage.
It will sell for $250 (with "premium" headphones).
Available only in black (to start).
Screen size has increased to 3.2-inches (from 3-inches).
Dimensions are 61.1 x 108.2 x 12.9mm (2.4 x 4.25 x 0.5-inches), some 1/3rd smaller than the classic Zune.
The classic Zune will now be known as the Zune 30 -- it's not going anywhere. More on that in a sec.
New flash Zunes

Zune 8 and Zune 4 are the names for the 8 and 4GB flash based models.
These will sell for $200 and $150 respectively.
Both will be available in pink, green, black, and red.
It will feature a 1.8-inch screen (compare to the nano's 2-inch screen).
Dimensions are 41.4 x 91.5 x 8.5mm (1.6 x 3.6 x 0.33-inches) -- compare to the new iPod nano, at 69.8 x 52.3 x 6.5mm (2.75 x 2.0 x 0.26-inches).
Everything else

New Zunes ship in November, date not yet announced.
All Zunes (including the Zune 30) will have a new, redesigned interface and feature parity. In other words, early Zune 30 adopters will have all the same software features as new Zune 80, 8, and 4 users.
Additional native video codecs for h.264 and MPEG-4 -- users no longer need transcode those file types to WMV.
WiFi sync to host computer.
Podcast support! (Sorry, no over the air downloads -- sync only.) Podcasts can also be shared via WiFi.
The 3x3 song sharing DRM has had its three day restriction removed, but users can still only play files three times.
Official press images, etc. coming shortly, don't wander far!

As we noted in our Zune launch post, with the new Zune announcements, Microsoft intends to do more than just launch hardware. The Zune crew has apparently done a complete overhaul of the Zune desktop software so it's no longer just a weak rebadge of Windows Media Player 10 (praise the heavens), which Microsoft hopes will help the social to get more, um, social-er, with a number of things to attempting better engage music listeners and Zune customers:

The Zune Marketplace is officially adding DRM-free music support, launching with over a million DRM-free MP3 tracks. As we mentioned earlier, other details (like which labels, whether there is a DRM-free upgrade path is for users who've bought music with DRM, price differences, etc.) are not yet known.
Zune Marketplace is also getting podcasts and music videos. (Great, but where's the real video content?)
Microsoft is also launching Zune Social, a free online music community / social network (great, another social network!) which allows users to create...
Zune Cards, which are web widgets not unlike Xbox's Gamer Cards. Zune Cards let other users track your most played and recently played music (updated each time you sync back to your host machine). Users can also sample music directly from someone's Zune Card.
You can now share with others music that was shared with you.
No, the Zune still doesn't analyze the tracks it shares, so Zune Pass unlimited customers still can't share music without DRM.
But, at very least the Zune's 3x3 DRM no longer has a time limit. Same three play restriction, but it no longer has to be within three days.
