Sony Vaio Pro now, or wait?

Alright guys, I recently bought a Sony Vaio Pro 13, and I still have a chance to return it. I got tempted by the Asus Zenbook Infinity. So my question is, when do you think the Zenbook Infinity will come out? And for how much? And do you think the Zenbook would have a better battery life than the Sony Vaio Pro 13? Thanks!
