Firstly, there's Square's Crystal Defenders R1, a port/remake/whatever of a mobile phone/iPod game belonging to the Final Fantasy universe it seems. PS3/X360 versions also in development.
The other three games are shown here:
There's Chindouchuu!! Paul no Daibouken, a "Famicom-touch horizontal-scrolling action game", as they put it. Or Sega's "answer" to Rockman 9. I think this 8-bit graphics trend is quite a bad joke, but some people like it and at least this doesn't reuse already existent material, so.
And finally Taito's Bubble Bobble Wii promises 4-player action, no less.
There's Tryfirst's Kiken Sora Iki (tentative transliteration) too, but it says it's a remote-based action game, so nobody should care.
I guess more than one of these were initially DS projects. Let's see if this doesn't stop here.
