NoE confirms Dr. Kawashima's Devilish Brain Training delay

Nintendo has made the decision to push back the launch date of Dr Kawashima's Devilish Brain Training: Can You Stay Focused? for Nintendo 3DS to optimise the best possible launch timing of this title within the European market. We apologise for any inconvenience this may cause and we hope to announce a new launch date soon. - Nintendo of Europe statement

Well... that is the end of that story. A bit of a shame to be honest, but if it helps the game in the long run, maybe it is for the better.
