Truthfully, I'd say that BanDai made a huge oopsie upon making the v5, starting with the v3.
v2: Once upon a time, there was a 'brand new' updated tamagotchi called the tamagotchi connection version two- everyone got all hyped up, and things hadn't changed much from the good ol' version one, other than some different characters and games.
v3: Suddenly, WHAMMO! you get to go onto a website called TamaTown, where you can do all the funky tama-stuffs you want online. They changed the Mametchi sprite in this version.
v4 & v4.5: Next thing you know, the phrases 'livin' the tamagotchi life' and 'your tamagotchi can get a JOB, DARN IT!!' bumped tamagotchis to another completely different level, making the older tamagotchis actually seem cooler.
v5: ...And there you have it. First your tamagotchis are getting jobs, next thing you know it's all [SIZE=14pt]TAMAGOTCHI FAMILITCHI MAMA-PAPA-MAMAMETCHI!!!!![/SIZE] ka-Blammo! Huge jump there. for the v5, though, the tamagotchi sprites ended up being lazy old 'the-first-on-screen-sprite-normal-then-the-bouncing-sprite-just-chops-off-the-bottom-two-pixels' sprites. plus, they changed the old Kuchipatchi sprite!!!! DO THEY HAVE NO RESPECT FOR THE ONE-AND-ONLY GOOD OL' 1997 SPRITES?! ->
<_< So, if BanDai wants to put a bigger screen on a tamagotchi, just keep it simple like the good ol' P1's and P2's. It would save memory bytes, anyway.
