Except that it's not... Each Pokémon on DS has outsold it's equivalent on GBA.

Wait, really? Not a single person? That is somewhat unusual, almost impossible if you ask me. Everyone knows someone, that group of people, who plays Pokemon. Unless you're like 55, I guess. 

But still, I wouldn't consider pre-orders for Pokemon really. As Black and White pretty much doubled preorders every week for over a month, so it should pick up soon. But yeah, it's not preorder happy. I mean, I haven't preordered it and I preorder almost anything.

I would judge your prediction on the performance of other games in the series as opposed to the trends you're seeing from Amazon and the like on this case. And that leads you to believe that Pokemon will do pretty darn well.

Watttttt? How much do you honestly think pokemon x/y will sell lifetime and by end of year? pls do tell...

10M lifetime seems around right.

So about 5mil less than the previous instalment? 

Using your logic, the past 3 gens, which have had much less hype than this title, went as follows:

16mil-18mil-14mil, though this is likely lower because it is the second DS title, and it's sequel launched about a year after launch. 

I think predicting less than Black/White sales for this is crazy, honestly. But everyone is entitle to their own opinion, so if you think 10mil sounds right, then fair enough.

That's just my prediction based on the preorder numbers on vgchartz and its position on Amazon. In terms of hype, no idea since I don't know anyone who plays Pokemon games.
