In my opinion this is not that great.
Nintendo can´t do so many things in 1 update.
They will take there time, if they do what you ask they will take forever to make the update. I love the ideas, but think how many time they´re going to take. Some months...
Better performance is a companion to the "stability stuff", and Flipnote 3D is just a release.
In that case, they need to edit three things of the console: friend nnid method, custom themes and DSi.
