How can I order an Ev3 gyro in Europe
The EV3 Gyro Sensor now appears to be on "general release" and available in both US and UK stores:
http://shop.lego.com/en-GB/EV3-Gyro-Sensor-45505 - these seem to be available in most EU countries the LEGO Shop ships to.



You can order the gyro sensor from the UK Lego Education site http://education.lego.com/en-gb/lego-education-product-database/mindstorms-ev3/45505-gyro-sensor.

OR

If you look at the shipping options in the US Educational site, it will ask you a series of questions to determine if the item can be shipped to your area. If no other options are available, they will ship to you for a fee and ask you to approve the shipping fee before they send it out. It looks like you can get the parts from Lego if you want them bad enough.
