Spheros R37 Full-HD+ oder 40 Compose Full-HD+

Hi,
I come from Denmark and my Deutch is nicht so gut... Therefore I write in English but can understand a bit German. Hard to find anyone that know thinks about Loewe in Denmark...

I have a old Spheros R32 DR+ and thinking upgrading to Compose 40 or the new Spheros R37. I prefer a TV-system/Sound-system with only one remote. I would by happy if someone could answer some of my questions:

1) Is Spheros R37 Full-HD+ and 40 Compose Full-HD+ the same technology or what is best? (I have seen different Kontrastverhältnis, Leuchdichte and so on in the technische Details but is it properly the same anyway?)

2) Is it possibly to use my old "Floor Stand 3" with the new Spheros R37 Full-HD+ ? (I have noticed that the new stands name is "Floor Stand 4")

3) Is it possibly to use the Individual Sound directly without AURO
3A) What is the benefit of using the AURO ? (I have sold my Centros 2102 because it was very slow and now I use my playstation 3 for DVD's, music and so on - and its great!)

4) Is it correct that I need the Individual Sound Subwoofer if I would like to connect Standlautsprecher, Sattellitenlautsprecher und centerspeaker and the new "Center Floor Stand I Compose"?

5) Can I just buy the Individual Sound Subwoofer and connect other lautsprecher - for example Canton (and still only use one remote, the ASSIST?).

6) If I connect a sound projector like Yamaha YSP-1000 direct to Spheros R37 Full-HD+ or 40 Compose Full-HD+ is it possibly to use the ASSIST remote to turn up and down the volume or do I also have to use a Yamaha remote?).

7) Is there any problems using the lautsprecher in Spheros R37 Full-HD+ as centerspeaker in any of the mentioned setups?

8) Anyone knows anything about Loewes future lautsprecher? (I have heard that there will be a sound projector like Yamaha YSP in the future?)

THANKS IN ADVANTAGE,
