I read the topic last night and what I think it is, is a normal V4 with a few more things; a cd for your pc, a personalisation kit (I would assume the egg thing would be white) and a few bits and pieces. I don't think it has any new functions and I think it's exactly the same as the V4. V4 hasn't come out in Australia (where I live) yet so I still have to wait for that.
Oh yeah, I forgot about the cd, you can download a little funny tamagotchi character smiley that you have to feed and play with on your screen. And it's like a microsoft word assistant, except it doesn't give you any help.
