Will there be upkeep in StarCraft II? What will be the highest number of upgrades for the shields, armor or weapons? Will the StarCraft II Editor be easy or hard to use? Will the Zealot charge ability cause more damage on the initial attack than on all other attacks? When selecting the Phase Prisms I noticed they have a 3rd, yellow meter below their shields and health. Is this meant to represent mana or storage capacity (warp-in capacity)?
