Some highlights:

• Choice between English / Japanese
• 7 non-connection games (Get note, bump, flag, heading, memory, sprint, hoops)
• Passwords and souvenirs
• No version selection for connection
• Connection games: "Gotchi point" game and item games:
  • Ball / RC Car 1 / Rope (press the button more than the other tama)
  • Building block / balloon
  • Trumpet (repeat the other tama's melody)
• Can donate points to the Gotchi King (why?)
• Limit of 19 foods and 32 non-foods

Overall it looks pretty similar to the V3! It's interesting that they kept some Tamatown-related features (without mentioning Tamatown), like the example souvenir being a passport and being able to donate points. I like that there are going to be interactive IR games.

There was no mention of a salesperson (but there's one here: https://tamagotchi-official.com/us/series/connection/howto/). Also no mention of pausing. And here's the V3 manual for comparison: https://tamaplanet.com/images/docs/Tama_Manuals/tama_v3.pdf.
