There is no V5. BanDai has released a new Tamagotchi Connection Version 4.5, which has many new characters, games, and careers. The V4.5 has a PC pack that you can buy for it and your tamagotchi can be in your computer, too. There are already many V4.5 out on Ebay, Toys R Us, Target, and wal-Mart. The V4.5 is still being distributed around the country so it may be in this part of a city and may not be in another part. It depends on where you live. There is a V4.5, but not a V5.
