V2 Aspect Ratio

Hi friends! Just wanted to open up a discussion about the aspect ratio of V2. Although V2 is not associated with Vine as Vine is owned by twitter, I wanted to know your thoughts on whether V2 should have a square aspect ratio or something larger? I personally am in favor of a square aspect ratio but I understand there are pros and cons, and Dom has posted previews of videos that have different dimensions. What do you guys think? Very excited about V2 and this forum!

Don’t know if your question has been answered but here
