The first comes from Hudson, and is a part of the company's puzzle series. This disc-based game (called Puzzle Series Vol.2: Illustlogic + Colorful Logic) offers 600 picross puzzles, only some of them are doubly hard since they involve multiple colors.
The second title is a WiiWare game that we already told you about, called Oekaki Logic. Is there a likelihood of either of these games getting localized? Probably not, unfortunately, but we really hope that Hudson comes through on this one.
