My son has a DS Lite and I'm going to upgrade it to a 2DS for Christmas. He says that he would like the 2DS Pokemon Moon or the Pokemon Sun version. I've looked at the price for the 2DS Pokemon Moon on Amazon and it is out of stock, however, the Pokemon Sun (have to pre-order) is selling for £89. Is it worth buying one now, or do you think that the price will drop a bit leading up to Christmas? Thank you.
