compatibility Xdj700

Hi There

I'm a happy owner of DJM 850 and pair of XDJ 700 for 10 years now.
Recently have seen some demos of DDJ XP2 and would love to purchase it straight away however 
I cant find the answers to questions I have in regards of compatibility and REALLY hoping 
You can Help me out!

1 is DDJ XP2 compatible with pair of my XDJ 700(using laptop desktop etc.)?
2 if it is,is it FULLY or limited features Only?
3 Can XP2 be connected to Decks Only(without need of laptop desktop etc.)

Anxiously looking forward to hear from you before I click Buy DDJ XP2

Best Regards 
Tom
