Check the Manufacturer's website for more info on Set B of the figures: http://www.bbcwdistr...roductid=10314.
It also looks like you can order the figures from that site.
It is unsure exactly how many figures will be released, but I believe that there will be at least 100. Also about the 300, I did hear in a video (perhaps the one that Atamaii posted?) that there are "300 characters in the Tamagotchi world". This does not necessarily mean that there will be 300 figures. I recently have been working on a project involving a lot of Tamagotchi Characters and found there to be around this many, so I don't believe they'll be releasing a figure for every character. Most likely the most popular/modern characters, (i.e. I don't expect to see characters exclusive to the vintage versions on figures).
About the release, it is believed that Set B will be released in Australia in December 2010, and it would be safe to assume they will be released elsewhere in the world around this time as well. The November release in Australia will most likely be the initial 3 designs on Tama-Go, as well as the initial 6 figures. However, if the other 3 Tama-Go colours and 6 Set B figures are released around this time as well, I'll definitely try to get pictures (if they make it to my local stores in time!)
