So... my initial plan was May - so takes my estimates with a pinch of salt!
However the current plan is that the network demo will be available by the end of the month, with the full game being "done" in November. Realistically though a release will probably happen in the New year.
If anyone wanted a new Dreamcast game to play online, Driving Strikers will be release in a month. You can pre-order this game at a early bird price...
