Honestly? Yeah, I want them to return. I thought about it for a while, and then I was like-
"Maybe they're super girly and pretty and crap, but with the animators being as great as they are... They're going to look freaking adorable!"
I mean, I've never thought anything from the older generations were cute. At all. But they could definitely restore the breezies to be absolutely fakkin adorable!
Also, it provides some more world-building for Equestria as it lets us see a species different to what we generally see, and some more of the creatures outside of Ponyville. Also, the title suggests the Breezies will be facing some sort of issue, also, it makes me think that the ponies don't realise they even exist. Quite an interesting thought, in my opinion.
So, even if the breezies are returning purely on the premise of making more toys, I think the writers could do a great job bringing them back.
