Thanks for the clarification, I thought since a bonus was already listed, that it would be the official bonus...didn't realize they added more to sweeten the deal.
That's pretty much exactly what it is. After the first week or so when sales slow down, they (often) add in another game or two to get people buying again. Anyone who already bought gets the bonus as well which helps promote early sales if you're familiar with how this usually works.
Yep. It's not a certainty, just convention. In the past it's common for the bonuses to be made up partially or entirely of games from previous bundles, but that seems unlikely here.
They should add in games from the last Android bundle just to confuse and anger people
