I really doubt they'll be dropping the FoC. Why include it in the codexes that were dropped last year? They had to know at that point whether they were going to be even having a FoC. Though I'm not a big user of psykers in 40k, I can definitely see how it would suck. Though again, I don't see how this would be happening as those same codexes still let you pick and choose psychic powers and what not. I think many of the radical changes are going to turn out to be just rumors and won't actually materialize.
"There is a cancer eating at the Imperium. With each decade it advances deeper, leaving drained, dead worlds in its wake. This horror, this abomination, has though and purpose which functions on an unimaginable, galactic scale and all we can do is try to stop the swarms of bio-engineered monsters it unleashes upon us by instinct. We have given the horror a name to salve our fears; we call it the Tyranid race, but if it is aware of us at all, it must know us only as Prey."
