How is the diaper bag design going?

Something based on the medium classic messenger/laptop would be great. No need to over think the design of it (saw the blog pic of the prototype). Just more pockets(in and out) and a changing pad and not to girly (guys carry diaper bags too!) Here is something close but I know you guys would do a much better job. Check out the Columbia Outfitter Expandable Diaper Bag.

I love my Timbuk2 bags so much and would love to have a diaper bag from you.
