K-ON!? Neither can the rest of Japan, but the bad news is, all good things must come to an end eventually, and K-ON! is no exception.
ANN reports that the popular manga that has run in Houbunsha's recently had a footnote indicating the next installment would be the last (coming out on the 9th of September). It was also confirmed that the final installment of (the fourth compiled book volume) will ship on September 27th.
Lucky for US readers, Yen Press licensed the original manga, so we can read it here. However, I have a strong feeling even though this manga is ending, we may see some other kind of spin-off in the very near future. After all, with a cash cow like K-ON! on your hands, who could resist?
