Here is a great example of what I was talking about with regards to debuts, from Wikipedia:
Humble Bundle for Android 3
The third Bundle based on Android games launched on August 15, 2012, and included Windows, Mac OS X, Linux, and Android-based versions of Fieldrunners (debuting on Linux), Bit.Trip Beat (debuting on Linux and Android), SpaceChem, and Uplink (debuting on Android), and their respective soundtracks. Those who paid more than the current average received Spirits (debuting on Windows, Linux, and Android) and its soundtrack for free. On August 22, games from the original Humble Bundle for Android (Anomaly: Warzone Earth, Edge, Osmos, and World of Goo) were also added to the Bundle. Charitable funds went to the EFF and Child's Play foundations.
Look at all those Linux and/or Android debuts! According to this only SpaceChem was available previously for both platforms. How in the world is Humble Bundle supposed to be able to do this after the THQ bundle? They will just wait for the next Windows only and/or Steam only bundle.
