What worries me is the lack of a firm time table. It didn't worry me at first, but as the months roll on....
Take it from somebody with infinite projects, loving the project can be a bad thing. I've got stuff like mamehooker that I haven't released in a few years because I want it to be perfect and obsess over the details. That's why I fear, not that he'll abandon the project, but that it'll be in production forever and in the mean time something similar will be released and we'll forget all about it.
We aren't at that point yet, but the "sometime this year" blurb worries me.
