Just going to put another two cents in, I guess.
Bandai America are aiming at 20-29 year old women. This is because during the vintage era, this group of people would have been around 4-13, which is where Bandai believes their target audience was back then. This is why they are promoting the vintage image of Tamagotchi rather than the modern image, because they are trying to bring back the older fans. This has already been said, but I thought I'd elaborate on it a bit. Just because somebody liked something when they were 10 does not mean that they will like it now that they're 26. Many people grow out of things such as Tamagotchi, and even the idea of getting back into them would not be considerable. I have an example of this; when Tamagotchi Connexions first came out, my sister (11) and I (8) both adored them. We absolutely loved them, and took them with us everywhere. It was actually really great to have a sibling who liked them as much as I did. When the V2 came out, we both got those. But by the time the V3 had come out, my sister no longer liked Tamagotchi. She was 13 at this stage, and I was 10. I continued on with my Tamagotchi fandom, and my sister did not. Now, at 15 and 18, I'm still a great fan of Tamagotchi, and my sister couldn't care less about them. I guess what I'm trying to say is, people grow out of stuff. Not everyone who was a fan in the 90's will still be interested in the brand, this is why it's a bad move on Bandai's behalf.
Moving onto my next point, the theory that Bandai are bringing out this merchandise to prepare for a Tamagotchi release. No, this will not happen, not at this stage, anyway. I can say this because Bandai have made it clear that they are not trying to make Tamagotchi a new, popular toy like they did with the Music Star and Tama-Go, but are ditching the idea of aiming to children and trying to aim to the old fans through everyday items and lifestyle wear. As a general rule, adults don't play with toys. Of course there are many exceptions to this, but the average adult would not be seen walking around with a Tamagotchi in their hand. Why would they aim a clothing line to 20-29 year old woman, yet still release a toy? It makes no sense on Bandai's behalf, from where they are aiming at. They might as well cancel the line and aim at children if they plan to release another toy.
Finally, the petition. Petitions don't work, at least not in the Tamagotchi community. Many petitions, such as "Bring Back Vintages!", "Bring Back Angelgotchis!" and "Release a Color Tamagotchi in English" petitions have been hosted on TamaTalk before, and obviously none of them have been successful. Bandai have said time and time again that they do not take fan submitted ideas, which includes petitions for a certain thing to happen. In fact, making a petition pretty much secures that what we want will not happen. It is NOT the way it should be - a good company would embrace the fan's ideas and throughts - but unfortunately Bandai are not one of those companies.
