Well it looks like it's already time for another StarCraft 2 beta patch. This time it looks like Terran has gotten a huge buff and the Protoss have taken another large hit. The Protoss Mothership has been significantly reduced in terms of HP and strength. Its cost in build time and food allocation has also been raised. This is good news for anyone who has been Mothership rushed (myself included). That thing was just impossible to kill and completely destroyed anything in its path. And then it promptly recalled itself home. Now it's significantly weaker and doesn't have that option for a cheap escape.

In addition the Zerg Corruptor received a +2 damage boost against massive units which should make this unit even better against Battlecruisers, Colossus, and Motherships (woohoo!). The Protoss Chronos also saw a reduction in its duration and most of the useful Terran buildings have had their build time reduced fairly significantly. 

Perhaps even important, the Terran Banshee now comes with the cloak ability. This will make the unit far more deadly out of the gate and more achievable. 

Overall I think these changes are farsighted and will benefit the game as a whole. I think Terran, if anything, may have just become the most powerful of the three races short of very late game. But this should help overcome the ridiculous cheap-ness of the Protoss late-game Mothership + Carrier + Warp Ray + Stalker combination. 

Here's the full changelist:
