A bit early to be talking about another TC as the last one wasn't "that" long ago. It used to be an annual thing (mostly around the summer holidays). Best bet would be to join/form a wargaming team, focus on that, and get more serious when a TC announcement has been made.
Being an active figure in wargames/plebmades also makes it easier to promote yourself for a future twink cup teams if you're looking to get picked up.
