I like the concept. Whilst I loved the design of the Raw models -- a great hand carry -- it's not quite as convenient for those pesky tasks that need two hands (like putting up tents in cruddy weather). So +1 for the clip on the reverse (removable clip or no? not sure what is feasible or what I'd prefer).
I like the minimalist look. I'm really not a fan of fussy fluting but then I tend to like the subtle cosmetic/ergonomic touches you finish your lights with. It'll be interesting to see what you come up with.
And damn do I wish I had variable brightness control on my WeeTi! Great feature.
I'm looking forward to finding out more: beamshots, weight, output, battery life and yes, price. Can I justify another addition to my Lummi family? I better start saving just in case.
