The Humble Voxatron offering came quickly (just one month after the previous bundle), which was already criticized due to its less-than-stellar game selection. In that case, the Humble Synapse Bundle pulled in $1.1M USD.
The key game part of this latest bundle was Voxatron, which is still in development (currently it's considered alpha quality) and this is the first time the multi-platform indie game has been available publicly. Other games like Gish and Blocks That Matter were then added later on.
The premiere of Voxatron managed to pull in just over $900k USD ($902,448.11) during its two week period. There was a total of 172,261 purchases, which puts the average price at $5.24.

There isn't yet word on what the next Humble Indie Bundle will be, but I suspect they will have their next deal ready by Christmas.
In related news, there's also a new pay-what-you-want indie game site out there now too. It's called Indie Royale Bundle. However, games on this site are not required to have Linux ports.
Also on the Linux gaming front, the Overgrowth game port to Linux by Wolfire Games is coming along. Below is a video of the latest Overgrowth alpha build.
