Q1, as defined in normal business terms, is the first three months of the year. Given that this is a tech company, the alpha may have a few unnexpected bugs that push back the release. Fear not though, it is coming and it should be relatively soon in comparison to when it was released worldwide.
A side-question: will it be possible to sync my PP game progress between my iDevice and my Android device? P.S. I am sorry if this question has been asked before
Yep, you'll be able to play the same account/island on both Android and iOS devices (which is handy for me, as I have an Android phone and an iPad!).
I've double checked, and you'll be pleased to know that the current plan is to have a non-FB option for synching the accounts, but we're also looking at adding a FB option as well.
Oh, Happy Day. For someone who would rather dive into in a ball pit filled with promiscuous porcupines rather than use FB, you have MY thanks as well, Midoki!
