I actually think male characters have more variety in designs. Most of the races are fairly 'equivalent' between the genders: Midlander = generic human; Highlander = muscular; Elezen = tall and thin; Miqo'te = slightly smaller than Midlander and Lalafell = potato.
The outliers are Roegadyn and Au Ra. While they have their unique traits, female Roegadyn are built similarly to Highlanders, and Au Ra similar to Midlander/Miqo'te - but the males are different shapes that aren't comparable to any of the other races. Both tending towards the 'hyper-masculine', as you say, but it's still a wider variety of actual designs available. They also have more opportunities for a range of character ages - though it's arguable whether that's a good thing or not, as few people use the older faces available, and it narrows the options for other designs.
Overall there are still plenty of designs possible to have a "non-hyper-masculine" male character. Midlander, Miqo'te and Elezen all tend towards 'softer', less imposing characters - though of course it's still very dependent on exact face settings and clothing. That goes for the other 'tougher' races as well.
I made a male Au Ra alt with the specific intent of making him as "un-fierce" as possible, and I think it worked - granted, he's still seven fulms tall and muscular, but I wouldn't consider him hyper-masculine, even if the default Au Ra design is.
I definitely thought she was just talking about the ears. Hopefully a design with the ears a bit further apart so they look more like extra-large elf ears - they seem quite awkwardly placed so high on the head like that.
Just going from the pictures - while their ears do seem to be on the short end, it looks like they're not actually cat-like, but just partly hidden in their 'mane' so the part that sticks out looks cat-like.
That's my line of thinking on the male designs too - I think they' have potential as an interesting mix of a 'feminine-ish' base design with the 'strong warrior' build implied by what lore we have. Some of the old concept art is along these lines, and I think it looks like an unusual and interesting character design.
Hahaha, I think it gets more interesting when things have logic in them, over "whatever looks cool"!
I do try to stick to less-improbably-sized weapons for that reason, too.
That's definitely an option too, but I feel like we'd end up with something closer to male Miqo'te in that case - not the "cute bunny boy" design from the concept art that people keep bringing up hopefully.
In any case, that concept art was designed as a counterpoint to the equally cute bunny girl standing next to him - and we didn't get female Viera in that style, so I greatly doubt we'd get that male concept either. At a "free to go anywhere with ideas" point, there was nothing wrong with it, but now that we've seen the designs for 'our' female Viera and heard the lore regarding the males, he would look very out of place.
(And yes, we "could" still get a second tribe with cute designs for both genders, but it doesn't seem to add up with what the Dramaturge described. He only said the tribes were dark- and light-skinned, and with only the single description of their culture, there seems little reason to expect such a different design.)
