B&H Photo has K-3 and the HD Limited lenses, which are available for pre-order.
The Pentax K3 is in transit as are the Pentax HD lenses. It will take some time to get through them all, but I plan on covering the K3 and all the HD Limited lenses, partly on being so impressed with the feature + quality + usability synergy of the Ricoh GR.
Shown below is the silver premium edition, which includes the battery grip. I am not a fan of larger and bulkier in general for carrying a camera, but I do like the 'mass' for shooting, so I’ll have to see on that aspect when I try it.
