For those who have not heard of it, GameHeart is a widely popular overlay for StarCraft II that allows observers to place team and tournament logos, draw analysis on the map, zoom out much further, and more, a video of which can be seen here. Gameheart has been used in multiple tournaments for quite some time, but never in a WCS event. That is about to change with the recent announcement of a collaboration between Blizzard Entertainment and the creator of GameHeart, Ryan Schutter, that aims to create a new version of GameHeart that will serve as the official WCS tournament overlay for all of the WCS events. Furthermore, this official WCS GameHeart Overlay will be available for anyone to use on any broadcast, even ones not related to the WCS.

This collaboration, announced by Blizzard on the StarCraft II home page, seems to be fairly new, as there was no information provided about new features, functionality, or design of the new GameHeart. Details are promised to come as the project nears completion, which will most likely mark a milestone for StarCraft II eSports broadcasting.

Lately there's been a lot of talk about the recent changes to Hellbats that allows Terran players to severely pressure Zerg players and hinder their economy. A few blue posts have popped up around the Battle.net forums, written by community manager Psione.

Our intention with this change was to allow Terran to apply more pressure against Zerg in the mid-game. So far it seems to be working out well, but it's still early and we'll have to see how Zerg players adapt. We'll continue to keep an eye on how this change is affecting the TvZ match-up.

With the recent update, we've been gathering feedback on the Hellbat change and observing how it's affecting the different match-ups. From what we've seen thus far, it's helped Terran pressure Zerg in the mid-game and slow down the their economy.

While we feel this has helped the match-up overall, it's still early and we'll need to see how strategies are altered to account for increased Hellbat usage. Often when a new balance update is applied we see a period of time where players adapt to the changes by creating new strategies and eventually counter strategies. It's important that we allow time for these kind of shifts before considering if further changes are needed.

It seems like the changes will remain in place for a while longer, just to make sure that Zerg can or can't adopt new strategies in response. Here's to hoping a conclusion is reached soon.
