It would appear that the new game is that fancy Nobunaga's ambition game.
Gosh, I hope this provides something new for the Pokemon franchise. Certainly, spin-offs don't do well very often, but I'd excited to see what new systems will evolve from this game, if any at all. From the trailer I saw...
My god that's amazing good sir! I didn't think someone could actually do it, but here you are! =P Super excited. I hope that Notch sees this and buys it from you (Unless you don't want him to, then nevermind), it looks like a great idea and I'm glad someone is finally making a MC DS.
On the contrary, there is indeed an ebook reader for the DSi. I have an AK2i, and I use IkuReader. It reads .txt, as well as two other formats. It might be new, that's why. http://gbatemp.net/t275315-ikureader-an-e-book-reader
