The Xbox One needs an official price cut for Europe.

You can alreay get a Xone for 300 euros here, and that's why it will probably be "official" at E3, or a little after (same for sony).

For amazon.fr :

Amazon.de got even better deals most of times, same for amazon.it

Dropping the price even more won't help, remember the gamecube ? Except Uk, Europe don't really want Xone/prefer ps4, it's already a lost cause.
