I don't believe a fully integrated Class 3 EFB will ever be available for the A320 family and the associated integration with the ECAM .
However having the new format on a Class 2 still has lots of advantages ie being able to jump straight to the relevant procedure in the navigation tree, cross linking between FCOM/MEL etc.
There are also some interesting features introduced that you can't see from the paper output. For example Airbus have introduced Knowledge levels for each procedure. By default you only see the basic need to know information, you can then select to see level 2 information which is "Nice to Know" reference information and level 3 which is additional information for all the geeks out there.
Also you get multimedia such as animated system schematics, clickable panel maps etc.
