Wish that were true. The new FAQ hasn't eliminated the limits to psychic powers on page 67. If the Inquisitor comes via deep strike w/ the terminators, he's stuck for a turn without prescience/blessings.
What the FAQ clarifies confirms is that if the psyker is on the table already the previous turn, he can can cast a blessing on a unit that deep strikes/outflanks/reserve move provided all other limits are met, e.g. units in range, unit is a legal target, LOS, etc.
Don't get me wrong, for his points cost, a Mallus Inquisitor is pretty awesome sauce already. Getting prescience off with a deep strike would take him to banana level brokenness.
What I see for the Vindicare now is a good choice for taking out models like Vet Sergeants, Icon bearers and standard bearers, Ork Nobs, etc... That, and Vehicles as well.
