In the latest Wizard101 Newsletter, which came out earlier this week, KingsIsle has hinted at new content coming this Summer:
"We're all getting very excited to "launch" into the summer season and a busier time in Wizard101. We've been hard at work behind the scenes on new things that will be catapulting your way soon."
Judging by the textures, this new content is clearly related to Avalon. You can tell the textures are the same that were used in the Avalon Castle Plot. Could it be an Avalon expansion? A new Avalon bundle, perhaps?
We're just a month and a half away from Summer, so we should know more about this in the June Newsletter or during the next KI Live!
What do you think it is? Leave a comment below and let me know!
