This is the new Nintendo 3DS XL that is not out in the uk yet and won't be on general sale here until some time in 2015.
The system is 100% compatible with all UK DS and 3DS titles due to the PAL system and Nintendo region settings and this is covered by nintendos WW warranty. The price of this is the same as a new current gen 3ds xl in most places but this has the faster processor, nfc, extra control buttons and better 3d screen.
This is a great price as when it does go on sale here I would expect it to start around 200 so you get a better 3ds for a cheaper price that will work with games from the stores over here with no issues.
This is shipped from the uk so you can get before Christmas and with no import costs on top.
