Nova, Amazon usually doesn't take out the preorder money until they ship the item.. This is mostly due because of "quantity" issues. If they take out the money and they don't get a large enough supply then they have to refund.. Which i'm sure they would rather not do.
Bidoof: EB and GS in the US/Canada are the same stores. the collectors edition is a North America thing.. soo, it's no suprise Canada has it.
As far as the EU though, well it's no suprise they haven't said anything yet. The waited until closer to release with 3U as well due to the bundle. Nintendo/Capcom are also likely waiting for a confirmation on the N3Ds release date for Europe. If that's what they are waiting on then it's likely they will offer a bundle or special edition MH4U-N3Ds combo.
