3DS/Vita Resources

[leokicklighter]

Firstly, my most sincere apologies if this is a stupid question, yet I still feel compelled to ask; why, pray tell, has nothing from either the 3DS or the Vita been successfully harvested yet? Forgive my ignorance on these matters; I've always been a big fan of sprite art and the like, but I know little to nothing about the science behind the ripping process.
