Spirit of Winter?

It looks as though the Snowshoe Rabbit isn't the only pet getting an overhaul in Wrath. It turns out the Spirit of Summer will be abandoning its red glow in favor of a bluish tint, making it appear more like a Spirit of Winter. The name of the pet will remain the same and the model will still be a red wisp, but the ambient glow will appear blue (as pictured here). It's unknown whether this will be a permanent change or just a little wintry adjustment until the next new expansion. My thanks to Jasmyne for submitting the screenshot.
