According to Zynga (as reported by Games.com), the new gift wishlist will allow you to add game items that you’d like to receive in the hopes that generous friends will answer your pleas for said items.
This will eliminate the current need to beg and plead to your friends to give you a specific item, and will allow users to customize their gift-giving sprees. That is, instead of sending out 30 of the same item everyday, you’ll be able to make all of your friends happy by giving them exactly what they want, and they can do the same for you. Everybody wins.
There’s no official date set of the release of this new feature, but the podcast said it will be sometime this week.
