Snacky Chan and Maniac are now longer part of the (revolving) group Uptown. They both left the group and formed their own crew called New Dynasty. They did a recent interview with TBS eFM 101.3, which is an English radio station in Korea, talking mainly about their experience with the Korean music industry and being in Uptown. From what I gather, it seems like these guys are done with the K-pop idol scene and want to start making music they believe in, hence the formation of New Dynasty.
They should be releasing a music video real soon but in the mean time here's an unreleased English track from New Dynasty called You Da Man.
