Chances are you're familiar with Phalanx one way or the other - Originally released for the Japan-only Sharp X68000 and later ported to the SNES for all regions, the game's somewhat infamous for having some of the most ridiculously inappropriate boxart of all time.
Of course, the game itself is actually pretty good, which already led to a Game Boy Advance port of the SNES version in 2001, and now a full remake for WiiWare. It looks like it'll stick as close to the original game as possible, only offering enhanced graphics and (presumably) audio.
Perhaps the developer, Zoom Inc., has chosen to remake the game to circumvent the price of SNES Virtual Console games, because it'll be very cheap indeed - It'll be yours for just 500 Wii Points.
Zoom is also making a new WiiWare puzzle game called Fantastic Cube, which will cost 800 Wii Points, but it doesn't really look that interesting - Once you've seen a handful of "match up blocks of the same colour" games you've seen them all!
Both games are currently only announced for Japan, and don't have exact dates yet, but we'll be sure to update you if they're announced for release elsewhere. In the meantime, you can view some screens of both of them here.
