From what I've heard (and granted, I don't have a source aside from another forum), there are actually going to be the same number of units per race as SC. Dragoons are replaced with Immortals, we know that

- otherwise, only the devs know.

As for superweapons, I'm hoping to see an accurately-sized Battlecruiser for the Terrans, else the nukes will fill that niche. The Zerg... I dunno. Maybe a giant bomb-dropping Overlord variant? Or more infested units? (Infested Mothership? :D)

(Wow someone answered :P)

Yeah the battle cruiser was a tid-bit small compared to the one shown in the opening cinematic of brood-war. Also I do the hope the nukes are a little bit more devastating than the ones in the last games. I was content with em but I mean come on its a nuke.

I dont really know about the zerg either but more infested units would rock mayby infested fire-bats and/or medics or mayby an infested zealot (that would be sweet) but anyway a new infested ... anything would be awesome.

Also I already knew the remaining dragoons will now be called immortals but is I wander if the material needed from dragoon productiong was exclusive only to Aiur? Or did they just get lazy and not build a dragoon factory between starcraft 1 and 2?

BTW there is an announced terran unit....Jump Pack Trooper! and man does that look cool! Too bad im a protoss all the way though...=)

to the question regarding number of units, blizzard said there will be only a few more units then in sc, and many are getting replaced. so there are alot of new units, but not adding onto the units from sc

I've seen demos of the game if ou have not, the terran and the zerg don't change too much. I saw that the battle crusier is stronger. Also the nuke is way strong. The zerglings can mutate into suasidal thingys, but the Toss change A LOT! Their units are much stonger, and they got lots new units too... theres the immortals and the stalkers, these wraith like planes (but stronger) Planes that have powerful lazers, these wierd quadpod things and a mothership. possibly more than that.

the reason terran and zerg havnt change much is because they havnt done much work on them yet. they mostly focused on protoss so far. so there will be the same amount of changes to zerg and terran as protoss. and as i said, the immortals and stalkers replace dragoons, the phoenix (the plane thing he said) replace the wraiths etc etc

What i've heard ( and have not had confirmend by anything official) is that the zerg will get a new build the heart of torrath (whatever that ultralisk hero is from the first starcraft) and it'll spawn torraths

I hear there WILL be new updates for everything.

Oh, NOW they introduced the Phoenix. NOW, after they killed it in Beta/Alpha SC...
