MBP refresh chances?

I am about to purchase a 13" air soon, but I just like the way the pro is built. I'm just not too sure I like the airs slim design that's tilted a bit.

Anyway after the lack of any mbp information at wwdc, what's the chances that the non retina 13" MBP will see a haswell refresh, and when?


Sorry if this is a noobish question, i'm new and not sure how these update cycles work.
