Sonya is one of my absolute favourite characters in MK, and have been since MK1, so I would LOVE to see a company like PCS produce a quality statue of her. The new Kitana and Mileena are gorgeous, and I loved the previous MK9 Kitana, so a similar statue of Sonya would be amazing!
If Sonya was to be made, here's my personal wishlist for costume, in order of preference:
3. MK vs. DC
Sonya's design in MKX has been depicted as really cool-looking in artwork, comics etc, but I really hated how she looks (and plays) in the actual game.
Judging from the recent Kitana and Mileena I'm sure PCS could make a sexy and badass MKX Sonya, but I would prefer a version based on an incarnation of the character I really liked.
