Yes they will. We will release more information in the future. But we have started to unlock some of the pages on our website about this stuff:

Natively they function in Ultralite™ mode. But if you have a compatible device with the AB Elite™ engine in them then you will be able to get firing solutions as far as you can range.
Once you are in external mode the firing solution appears in the bonded devices. That is the binos, external device, and scope all at once. So all 3 will update together.
You are correct. You can set up to 8 customized points. You would simply tell the scope what distance (yards or meters) that you would like, or what hold over (mil and moa choices). You can then build a custom reticle with those holds programmed in. So what you would do is laser say your 5 targets. Then go in to the scope, put those 5 distances in as the reticle points, turn on only the 5 points and go. You can turn on/off what you want up to 8 hold overs.
They are already shipping.
Wind and Elevation. Its the full firing solution when being used in External Mode just as if you hand typed in the range to the Kestrel or Garmin.
I would expect the 3000 BDX Binos to hit around SHOT Show.
The BDX Devices only read range and inclination. They do not read atmospherics. You have three methods for solving this.
1) You can use the BDX App:
http://appliedballisticsllc.com/products/apps/sig-sauer-bdx-app/ and pull the weather from the internet.
2) You can hand input the atmospherics you want in the app.
3) You can pair it in external mode and use the compatible external devices sensors. At this point, the BDX device is basically feeding the range in to the compatible external device and then returning the ballistics solution that device generated. Elevation, Wind, Secondary effects etc.
Currently only the 2400 BDX and 3000 BDX LRFs function in external mode. The 1400BDX, 1800BDX etc. are limited to AB Ultralite™. When it comes to the scopes it does not really matter.
