So what exactly is coming with extended C++ support?

Great.

My thoughts too. Seems like maintenance hell.

I use both std/boost and exceptions when makes sense - game is 
not just rendering and number crunching after all.

Tbh what I -am missing- is proper run-time support for what is 
already suppose to work (building x64 C++/D app crashes when 
calling writeln() from D side). Win32 support is coming but I 
expect similar problems (is nobody really mixing C++ and D using 
VC++ atm?).

It would be great to be able to call non-virtual members of C++ 
classes from D but
I don't really need anything else from the language SPECS to 
start things going - my question is out of pure curiosity.

That being said my biggest fear is that D2 will never be 
finished... I am lurking on those forums for 2 years now, waiting 
for the signal to start the transition but I need to be sure that 
in few months everything I need and the code I write will work as 
expected (and on iOS too). I am not seeing this unfortunately, 
language is still being actively discussed on the most basic 
level (allocators, ARC, auto-decoding of utf strings...). It 
looks like Phobos might need to be rewritten entirely and soon. I 
will not give up tho, if I must skip D for one more project 
(which lasts year or two) then be it, hopefully I will be able to 
use if for the nest one :(
