I know this might be kinda old and the LE vs SE rant might be over but I have one more thing to add:
For those people claiming that they will just go for the Microsoft deal on the SE, you are forgetting that it is $25 off your next order. This means that, knowing Microsoft, you need to spend MORE than $25 in order for you to get 25 off. Most likely it will be $25 off your next order of $40/$50 or more, so you can’t expect to get 25 off the WGMP because it IS $25.
TL;Dr:
You wont be able to get the WGMP for free with the Microsoft Preorder deal because you may need to spend at least $50 or more in order to get that deal.
