I'm in the US and my SA just let me know that they're not available for pre-sale yet and typically they don't do pre-sales for limited edition pieces so maybe it varies from store to store?
I am in US too, no pre-order for all canvas items for any new collections. If you have a CA you can tell her/him to put pieces that you like aside and when they’re able they can charge you on the launch day. As far as order it thru concierge, I haven’t done any so I have no idea. Hope this helps a little.
