Blizzard has released possible changes in their June 14 Balance Testing blog post.
Protoss Changes
Warp Prism
Movement speed increased from 2.5 to 2.953 (previously 2.5 to 3.375.)
Acceleration increased from 2.125 to 2.625 (previously 2.125 to 3.25.)
The Gravitic Drive upgrade has returned to the Robotics Bay and will increase movement speed to 3.375 and acceleration to 3.25 when researched.
Terran Changes
Hellbat
Attack damage decreased from 18 +12 vs. light to 18.
The Infernal Pre-Igniter upgrade increases attack damage from 18 to 18 +12 vs. light.
We’re haven’t decided whether or not Hellbat drops are a problem yet. It’s looking like it could be, so we’d like to try a nerf in this balance test map.
Banshee
Cloaking Field research cost decreased from 200/200 to 100/100
Cloaking Field research time decreased from 110 seconds to 90.
Zerg Changes
They are already OP as they are now so no buffs for you.
