Once I just looked at this as a GI Joe Kickstarter, the samurai just didn't seem necessary. I honestly don't ever remember Budo in any format other than recent figures, so it was just Tommy and the Red Ninjas that I needed. But the black ninja look is just the iconic go-to so I needed some of them at least so it just ended up being a good idea to stick with the all-in level and add a few bare arms in.
I'm glad this is picking up steam now. I was skeptical it was even going to reach initial funding, let alone stretch goals. I think the first wave of stretch figures will happen now, but I'm not sure beyond them right now. I'm still skeptical on the samurai actually happening, but its still certainly possible if things keep progressing!
