I'm sorry for continuing to steer this thread off-topic - we're meant to be discussing the designs here, there's a
separate thread to discuss the unit itself - but I really wanted to respond to the recent disappointed posts! Because personally, I'm still very optimistic.
I am
extremely excited about the PC pack that's coming out with the 4.5 (see
Black Candy's thread for more details). If it's only compatible with the 4.5, that will be a huge incentive to buy it. The PC pack does come with its own exclusive 4.5, but I usually feel compelled to buy two of any type of Connection, to see all the connection features in their full glory. I would feel like the coolest girl in the world with my Tamagotchi docked at my computer like an iPod, with voice recognition...!

And to have my character animated and fetching my email - adorable!
Also, don't forget that all this stuff is scheduled to be released in the fall, if I'm not mistaken. Just because you heard the press release at a time that seems much too early, don't forget that it will be some time before the stuff actually hits the market! By then people might be ready for a new Tamagotchi.
But in my opinion, the unit itself is not the exciting part. It's the peripherals that they're releasing that seem really exciting and innovative.
I am also optimistic about what it means for them to be doing a "mid-year refresh" by releasing a ".5" version. Sometimes this means that they're biding their time, keeping their product in people's minds, while they finish up the research & development for some awesomely new product!
PS, maybe we should shift all the posts not specifically about the designs and put them in Black Candy's original thread?
