Yep, Hasbro's actually redesigning the G3 line for fall! Someone on the LPS forum was calling them G3.5s, which I think is cute.
Here are some videos!

Big focus on customization and "decobits" and themed playsets. The style has become even more dynamic, and from the looks of it, the heads may still bobble like the later G3s. Lots of characters from the TV show, including Madame Pom, Sugar Sprinkles, Minka's turtle pal, one of Vinnie's dancing lizard friends, etc. There will be repeats of the core cast with different expressions and poses, but also a LOT of new unique pets.
G2 did also make a return! Nothing displayed at Toy Fair but I think Hasbro recognized that the G2s are very loved and missed and may continue to produce them simultaneously with G3.5.
So yeah, G3's getting an upgrade this year, while G2 is getting an encore.
We've also got a couple waves of blind bags that are G3 molds with the older G2 style eyes. One has Minka as a chase pet, and I think the wave after that has Zoe.
I collect all the gens so I'm pretty excited about everything!
