In this paper, we present the latest AO simulation results done at ESO in the context of the E-ELT. We present an analysis of a potential failure mode (a broken concentrator, which tilts a group of 7 segments). We look at the behavior of a cascaded AO system, where a low order system is fed into a high order AO system, in the context of PCS, the future planet finder system for the E-ELT. We then investigate what happens if we do not use modulation at all an infra-red pyramid sensor (in the framework of METIS). Finally, some very preliminary points are investigated about natural guide star sensing in a tomographic AO system.
