1) Can an upgraded command center be salvaged? Does it lose its mobility when upgraded to a surveillance station? 2) In Starcraft 1, when you cancel a nuclear launch that is in progress, you lose the warhead. Will Starcraft II make any changes to this setback? 3) Can a Ghost be equipped with both a Nuke and Drop Pod simultaneously? 4) Will "caster" units, such as the Protoss High Templar, have a regular attack, like Tassadar had in SC1, or will they only be able to attack through their spells? 5) Can Marines be Stimmed while in a bunker? What about a Ghosts snipe ability?
