Series 9 will be released in August and series 10 Nov./Dec. this year. We'll get the pics of the new series in early June so I'll hopefully can show them to you soon!
If this is real, it means they are trying something pretty different for this wave. Same character, but 3 different facial expressions and outfits/hairdos. I think it's a pretty nice idea! Pinky faces being pretty simple, it's normal than after a while they would start looking like each other... so having one character per wave isn't bad, but having expressions is great! (Look at that pout!) 'Would be fantastic for funny expressive photos, even more for picfics.
Sadly some of those parts look like repaints, but I like the faces and hair so much I feel it's nitpicking. Or maybe this is actually how they want to handle repaints from now on? I guess we'll know with the next waves.
