Pi Zero version

Hello, thank you for making this great board! I plan on testing this board against a WM8731 board to see which design is better for me to use for my project - https://hackaday.io/project/159744-pi-portable-recorder. From what I understand this board should be better as the TLV320 has a better sampling rate than the WM8731 and has several other key stats better than those of the WM8731 (I am yet to check the datasheets to confirm this). If I decide I like this board, I plan on making a Pi Zero sized version due to the space contraints of my portable device (I see lots of unused PCB space on this version), but before I do so I just wanted to a question - are you already developing a Pi Zero version?

Thanks, Louis P
