SC should especially like the achievement. Steve explicitly said they're looking for ways to add more loot without adding collector levels or bonusses. Well.. there you have it. I'm not sure why I say this though, we all know it, they just won't do it. Best to leave it at that.
On topic: Don't be ridiculous OP. That will never happen (all upgrade at the same time) and even if it would, it would even out again after a week or so.
