Seriously, after thinking for some time I think I'd rather have them only in japan, here they would be extremely expensive, I'd rather buy a japanese cheaper one than buying the same version in english for double the price xD
I'm saying this because the Tamagotchi Friends is selling in the UK and Europe for the same price as an iD L.
while the iD L is about 25 pounds in japan, when the english version came to harolds in the UK they sold it for 60. (And that's about $90 I think?)
The price in the US would probably be more reasonable, since the Friends is half the price than what its in the UK, but still, inporting a japanese version would be much cheaper xD
Also I'm pretty sure an english version wouldn't have the download feature at all, the iD L english didn't got any english downloads (I'm glad they still work with japanese downloads, but they could change that in a future colour release)
If you really want a colour version and don't want it to be japanese buy a P's, it has an english patch, or wait for the 4U, since there are plans for making a patch for it too xD
the 4U is much more expensive though, so if you are looking for a cheap colour tama go for the P's. and if you don't mind Japanese go for an iD L, you can easilly find them for around 20-25 pounds in ebay sometimes.
