Release dates are not set. I'm doing the above when I want to, so it will be a while. WiiMoveIt is the current project that I'm really working on, but I have two more idea projects below it (and GRiiD will be incorporated into WiiMoveIt).
Well, I plan on becoming proficient in C++ as well as maybe some Windows API (because that's like a new language on its own). I would also like to develop something decent for the Wii, and I have a project I'm starting (WiiMoveIt), but it will probably take most of the summer for me to get it to work right. As for my programming background; I have no background. I started self-teaching through cplusplus.com and cprogramming.com tutorials in February of 2009. After getting the basis of C/C++ I now also learn from looking at source code.
Well as for Wii HomeBrew... I read about it a few months before January of 2009, but never did anything. Then, in January, after renting the infamous Zelda game for the Wii and using the Twilight Hack v0.1beta1, I got homebrew while at my grandmother's house. Much thanks to Team Twiizers and anyone who helped with Devkit Pro.
