Jürgen, this is a really tough question answer. If you want Urbis to make money as a commercial product, then you'll likely need to tie your world to a system.
Eventually, yes... but I don't think it is necessary right now.
Races can be described in all sorts of systems. Many monsters are common enough that using them in different systems won't be difficult. The main sticking point would be the magic system - and the model of D&D 4E, with its split between arcane magic, divine magic, and ritual magic, can be described without references to specific game mechanics and then adjusted to different game systems.
