X and Y definitely won't garner HG/SS sales, much-less the "golden age" sales. Can't predict day one sales.
If by ''Golden age'' you mean Gen 5, then I agree.
IIRC, Black and White were the pokemon games with both the most Preorder of all times as well as one of the most imported games too. And as an above poster said, Gen 6 actually is getting a lot of older fan who gave up after gen 1-2 to come back into pokemon. One of my friend's latest Pokemon game is actually pokemon Yellow. When I showed him the XY tralers, told me he will most likely buy at least one version. (though he alreadt have a 3DS so he won't ''buy one just for these games'')
