While the new Zeiss Ikon camera looks nice I don't think it will live up to it's price tag (thinking of Rollei's expensive Cosina rangefinder).
Personally, I would go for a Bessa setup if I had the funds:
Bessa L $69 (cheap rangefinderless body to be used with the 15 and 21mm)
15mm f/4.5 $345 (plus screw-M ring $55)
21mm f/4 $335 (plus hood $45 and screw-M ring $55)
40mm f/1.4 $349 (plus hood $45)
75mm f/2.5 $299 (plus screw-M ring $55)
2 Soft Shutter releases $15 each
This is a total of $2281, which is over $500 cheaper than the cost of JUST 1 Black Leica M7 .85X camera from B&H (that's right, NO lenses).
Take away the 15mm (a luxery in my opinion because of the number of shots it would be used for) and you come in under $2000 ($1881 to be precise).
With this setup I could photograph 99.9% of anything I would photograph today with 35mm. If I had even more hypothetical funds I would replace the 75mm f/2.5 with the Leica 75mm summilux or the rumored summicron and add an extra R3A body, but other than that I would be set. In addition, I would actually prefer the R3A and it's lifesize rangefinder to any other available in 35mm. After using a M3 for a while I loved the "floating frameline" sensation of shooting with both eyes open and the lifesize viewfinder in the R3A would make this even easier to accomplish. I'm already saving up for my graduation present to myself which will either be a setup much like this or a brand new Canham 5x7--we'll see which it ends up being....
