Today yet another group of StarCraft 2 fans have received, and are receiving, their keys.
Some IncGamers staff and StarCraft 2 fansites' staff that did not make it into the first wave received more beta keys today.
The news seems to confirm rumours that more keys would be sent out today.
If you are a key holder and not received your key by tonight or tomorrow, you're likely going to get into the following wave. We do not have an official word on the next wave yet, we assume blizzard are busy with the one which is still in progress.
