Before anything my condolences to Takamaru fans, we always need to take this kind of "hints" with a grain of salt.
But other than that I have been reading the last page about the negative reaction to Takamaru's deconfirmation in Japan. There are somethings to consider and not really go around thinking everyone is pissed, there is always the possibility that a minority is so vocal about it that made it seems everyone is pissed, and I am not saying they shouldn't be.
The thing here is it doesn't matter what characters are confirmed or disconfirmed, there is always going to be people pissed or mad because their characters didn't make to the game, despite being "obvious" choices, in that regard I prefer to stay on the pessimistic spectrum about the characters I want, in this case I fully supported Palutena and she was the reason I joined the site, even with the 3DS leaks and Gematsu I was always exceptional about it until the actual confirmation happened. Lucina was more of a pipe dream and was my 2nd right behind Palutena, but I never ever expected her, she was a surprise.
If you go to the rate thread and check Saturday, lots of people put Takamaru with such high scores because of the game reveal only to saw Takamaru deconfirmed yesterday. What I am trying to say is that sometimes it's better to be pessimistic that way expectations wouldn't be crushed so hard.
About that Lyn incident I don't know if it is real or an urban legend since that specific game is way more popular here than in Japan but I have to say there are more things in live than characters getting confirmed in a game.
We should be thankful with Sakurai for even bringing us the possibility to play this outstanding series, without him we shouldn't be here today, that is a part that I dislike of some people in general, it is always easier to point out the bad things, instead of being grateful.
But you have hope guys/girls Takamaru NOW stands a REAL shot for the next game, so I wish you luck
