So now we know that the NDA wasn't covering up any beta stuff.

Also important is that completing the missions gives you cash. No, not minerals -- real, actual cash. Also new to StarCraft II is the ability to buy upgrades and hire mercenery units. While on your ship, you can go to the second main area: the armory. At the armory, you can buy a wide array of specific upgrades for each of your units, and in some cases even unlock buildings. Want your medics to heal more quickly? There's an upgrade for that. Want your marines to do more damage? Upgrade.
EDIT: Lots of sites have their stuff up now

Hey,
It's the end of NDA so I can write what I'v discovered during the play in singleplayer mode.
After the game crashed (like 5 times during the whole press day) I switched to skirmish mode and suddenly on the build list
I had those units (and also in help mode):
Source: http://starcraft2.net.pl/portal/sc2/1/674/Nowe_jednostki_dostepne_w_trybie_singleplayer.html
Medic - we know this very well,
Firebat - also very well known but with orginal sounds from sc1,
Spectre - new unit similar to Ghost - can cast lockdown, nuke, halucination (zerglings, hydralisk, mutalisk),
Grenadier - new unit - he throws grenades and are really effective against groups of zergs
Vulture - with great animation of spider mines - orginal sounds from sc1,
Goliath - orginal sounds from sc1
DiamondBack - its a hovercraft that can attack while moving - like Cobra but the model is different
Wraith - also with Cloak
Hercules - really biigggg flaying transporter - you can put there your whole army and there is space left
And ofcourse my favorite new building:
Tech-Reactor - a mix of reactor features and tech lab, so you can build like 2 units in the same time and have all of them unlocked in barracks, starport or factory
ah, and the new gameplay: http://www.starcraft2.net.pl/portal/sc2/3/666/Press_Tour__lipiec__singleplayer.html
