As of now we only know about the default armour and a pair of greaves you can grab in the demo, other than that no, hope we get full body hard suits like in ME1.
^ I've seen that trailer, and I saw names like Ariake Technologies and Armax Arsenal on those armour customisation screens. It seems like, instead of buying full suits from manufacturers a la ME1, we're buying armour pieces from them now. It also stands as reasonable proof that DLC armours from ME2 will indeed import into ME3. Other than that, there's not much to go on. Terminator-HIX
