Warbasse has extended with Tudor so that frees up a spot.latest rider rumoured to join them is Mark Stewart. Before, there was talk about guys like Pickrell as sprint leader, Stefan de Bod, Larry Warabasse, George Jackson etc. + like 10 young Americans. So yeah, more or less as you say.
Owen Cole was also rumoured to be amongst the signings iirc.
Benson published an article about it a month ago or so
