I've heard that the V4s were glitchy and my little Olvia (Olivia) the Pyonkotchi is currently undergoing the name glitch, which made her Mlvia.... If they're going to release this V4.5 soon it'll probably be even glitchier.... Plus if they are doing a re-release of the Uratama to other countries than Japan, what'll they call the characters. Mametchi.5? They can't call the Mametchi on it Ura Mametchi.
MY V.4 too. He was XACK, until it showed him as a parent, then he was zack.
Also I hesrd V.5's come out next summer.
