I don't know if you've had the chance to see any of the panels or listen to how the dev team operates over the years... but 5.0 is pretty much done in terms of "what content is going to be included at lauch" and the art team is already working on 5.1. (Source Art Panel from EU Fanfest)
Viera, showcased by the Art team, would have been designed by them first. The idea that Male Viera is behind on development isn't logical with the factual information we have from the team as recently as last month. When the main person that was responsible for creating the viera concept art for the girls we are getting said she's already working on 5.1 things. That is a pretty big indicator.
But what's more? Yoshi openly tells us when he wants to show us things but they weren't ready in time. The new Savage series hit a snag and Yoshi told us flat out he wanted to show us but couldn't (Source Fanfest). So why wouldn't they just tell us that when they have a habit of being honest with us?
Having an opinion, being dissapointed in not getting something is 100% ok. But when you bash a dev team that has shown us time and time again they are doing what they can for us, with the resources they are given by even bigger SE and bashing them over and over in 160 pages of the OF? Nah, that's ridiculous entitled behavior.
It's ok to think you're getting something. As noted in the posts you probably didn't read. I am a firm believer that if the people asked in a decent way that we would get it eventually. As we did with the male bunny suits. But it's not ok to just be complete monsters about it to the team that can read these threads and works hard for us with the resources they are given.
Have compassion. Be a decent player base.
You're reading into his response, what you want from it. He can't speak about the male counterpart because it's sanctioned for release at the JP fanfest. That's not him saying "Oh Male Viera are on the way for sure". If anything that's odd behavior and it's super weird already they didn't address it out right. That is not hope, it's an opinion that people have that is morphing into entitlement.
