Pie and Beans
Look for me on the local news, I'll be the guy arrested for trying to burn down a Nintendo exec's house.
What has happened so far is that a big release causes 1 week of relatively high sales and then it just falls back down the next week. Very big problem since big releases are so far in between.
What metric are you using for big releases post-launch? Pikmin 3? 22k HW from 8k?
The bump last week was from bundling value (quasi price drop or as close as Nintendos willing to provide this year) not a big game release.
