Steam is getting (surprisingly) aggressive with their season Pass stance, not sure if it was mentioned here:
Steam now requires developers include a complete list of all DLC included in a Season Pass, a basic description of the content included in each, an expected release window of at least the quarter or season and year expected. Additionally, developers are only allowed to self-reschedule their release date one time for the Season Pass, and only up to three months later than the original date. If developers want to delay additional times or delay further out, they have to speak with Valve first. If developers don't adhere to these rules, Valve says it may take action in ways such as removing the Season Pass from sale or refunding customers.
^ I like this obviously..
