Looks like the rumor was false
I don't know if WB has confirmed this yet, but according to The Leaky Cauldron, it looks like Ralph Ineson has been cast as Amycus Carrow, which would put paid to last week's rumor that the Carrows were going to be students in HBP. I'd wondered just where the heck that would leave things for DH! But this actor is only a bit younger than me, so it'd take a helluva lot of make-up to pass him off as a teenager!
