That's like asking who's gonna win the Super Bowl. No one really knows for sure. Just have to wait and see what happens in the coming months, but with the min firmware check that they added to 11.0, I imagine it will be quite awhile before someone figures it out (if at all). I can't say that with absolute certainty, but from what I have gathered in my research, Nintendo did a pretty good job stopping soft downgrades for the time being.
Also, this would have been more appropriate in the "Custom Firmware and Flashcard" section. This is for Homebrew Development and discussions relating to that. Just to give ya a heads, don't be surprised if you get flamed.
