>>8668176I expect to see some brute wyverns announced soon, seeing as that group contains some of the most popular monsters in the franchise: deviljho, brachydios, and glavenus. Brachy would especially be complementary to zinogre, both of them being gen 3 monsters with bold designs.
As far as engineering, it seems to me that brute wyverns would have less issues than the flying wyverns we got so far. Brutes have thicker bodies and less fiddly parts like wing segments, making them more similar to godzilla sculpts that the company is used to working with.
