Is that confirmed by Riot? Surely they would have the same page on the EU site as on the NA site detailing the game and imminent order time/date.
Sure, confirmed by Riot.
If you are shipping to the EU, you want to use the EU store. It won't be populated until tomorrow. We should have a few 'products' in place that we will turn on as they're needed. Basically, if we sell out of the October order, we'll turn on the December 'pre-order'. If that sells out, we'll roll over to a March 'pre-order', etc.
But the EU store is the only store that can ship to the EU. So that's where you want to head.
