If you intend to practice your game, bringing your own console is the only way to guarantee that you always have a console available on which to practice. You are expected to bring your game and controller(s)/save(s) if applicable. There will generally be several of each console available, but not necessarily always. We also do need several folks to volunteer to bring those multiples of each console so that we have them available. That will be organized at a later date (watch for the "equipment" thread).
(edit) As always, clarifying that I am not a staff member, so my answers should always be taken with the appropriate amount of salt.
