I just want to say that your analyses are fantastic and I look forward to your next one, whichever one it turns out to be. Here are a few observations I have regarding your current work:
1) Why is Little Mac considered a new series character? His first appearance was in Mike Tyson's Punch-Out, which was released in 1987, barely a year after Takamaru, a character you listed as retro, made his debut.
2) Why only list Palutena as a viable Kid Icarus addition? I've heard plenty of fan outcry in support of both Magnus and Medusa, so it would, in my opinion, be hasty to count them out.
3) This is, admittedly, something of an oddball choice, but do you think you could add Monita to your new series analysis? Nintendo Land seems to be rather better-regarded by Smash Bros. players than the Wii series, so she might make a good 'shock' announcement, especially since she would represent the Wii U.
