Not many. Besides, I was at a convention yesterday here in Miami, FL where I am from and there were several Krystal supporters like me who would like to see her in Smash 4's DLC. Even one girl I met who I talked to was wearing a Krystal theme pants from Adventures that was custom made and it was awesome. I even have a Starfox Adventures shirt that I got when I was a subscriber to the Nintendo Power magazines to show my support for her along with buying Command on the Wii U's eShop a few days ago to show my support. As I said before, there is a big Japanese audience like us who wants her to be in Smash 4's DLC. Remember, there was a poll from Japan not long ago this year that for the newcomers, King K. Rool and Krystal are among the most highly requested characters for DLC over there in Japan and it's no different here for us Americans. Because they have been like that since Brawl. And with a recent turn of events of Zero coming out later this year (we haven't seen her yet or she may not even appear in that game; but she will be in future entries after Zero) and Command being released on the eShop recently, this really boosted her chances by a tenfold everywhere. I consider this to be a blessing for us Krystal fans/supporters than the opposite. Let's continue to press forward and do everything to make sure that she finally makes it in.
Right now for me, there should be no reason for Sakurai to ignore this again . More importantly to finally consider Krystal to make the cut. At this moment now he should be aware of Miyamoto working on Starfox Zero and the release of Command recently on the eShop and combine that of her having a huge fanbase and being a popular character. Even he was impressed from her bring the most requested female character to be in Smash since Brawl and there are people from the majority who still want her in. Not many characters who has a huge fanbase like her has a website dedicated to that character. That's why we need to press forward to spread the word everywhere including in the Miiverse especially if anyone plays on the Miiverse stage to anyone who plays as Fox or Falco to show comments on the background of Fox or Falco with Krystal with them to join them in battle. With the Starfox series becoming a big deal this year and relevant, it's time that the SF roster deserves some more representatives to join Fox and Falco.
