I apologize, but your way of thinking is incorrect, I have been buying games for years without fail and I have learnt that I must with all due respect, ignore the shop's release dates until I see a confirmed one on my local Nintendo's website which for me would be Nintendo of Europeand then when I see that, I make my decision to go through with the preorder or not.
@Lyla May I see where you found that information for all of 2011's announced games as I am quite interested in knowing just exactly which ones I can purchase before the year ends.
Here is a list Nintendo put out right after E3. It's for all the 3DS games they announced up til E3.
