I am looking forward to seeing the specs on the weight and cost as this is an important ratio, at least for me. I would strongly encourage some kind of neck baffle, it makes a big difference.
I would like to see some experimentation on a hybrid bag. Synthetic on the bottom and down on the top. As already mentioned down doesn't work good on the bottom of a bag. A lot of the lighter weight sleeping pads have a marginal R value and depend on the insulation of the bag to work in cold weather. I like the Big A sleeve design, but it takes a hefty pad to work in cold weather with the bottomless bags. I have the Dual-core and it still doesn't cut it, for me at least.
A lot of people get cold feet, increase the insulation in that area.
A sleeve for a pillow would be a great idea!
