I thought there was supposed to be several new items added to the gem store? Is that not happening anymore, or was the patch delayed?
The Gem Store is in the process of being updated, so those items will be available when the update is applied.
Game Update Notes are posted in the News and Announcements section of the forums.
We do not typically announce when on the day we are updating the game. This is due to unpredictable events that might happen on the day that may push us past a previously announced time, which would just frustrate everyone.
