Last December, it was announced that both Rockman-san and Rockman-chan would receive the physical tankobon treatment. And sure enough, Amazon Japan recently began accepting pre-orders! You can find Rockman-san volume 1 here and Rockman-chan volume 1 here.
At the moment, both titles are eligible to be shipped abroad. All you need is an Amazon Japan account and you're golden. They're expected to ship on March 4th for 704 yen a piece.
No word yet on the possibility of an official English localization. That would probably fall under Udon's territory so... go bug Matt. The fan-translations are readily available in the meantime.
