Sprinter 4x4 coming for 2015

I don't think it's going to be a "traditional" 4x4 with low lock etc, but sure will be nice in the snow and some back roads and even on some beaches. Definitely will expand the range. Can you imagine a diesel, class B from the factory without having to put on non oem 4x4.
As far as towing, it won't be great, but I don't think any manufacturer will build the perfect RV to make everyone happy all at once.
For me, towing 7.5K is good enough, probably more than I need, but the 4x4 Class B and a diesel is making my mouth water.
