Hi Juditha, i'm thoroughly familiar with the E.C. readings, and his guidance, to my knowledge, never once mentioned the specific year of 2012. 

  His guidance pointed out trends, periods, and general marking points when it came to the changes and the timing. 

  For example, Cayce's guidance mentioned an important testing period for humanity that would take place roughly from 1958 to 1998.  Besides being a testing time and one in which humanity would decided most of it's fate for later on, this was also said to be when the Earth and spiritual changes would really begin to be noticed. 

Cayce also mentioned for this time period when lights would start being seen in the clouds, which i take as a reference to UFO and E.T. phenom. and the explosion of both observation, experiences, and interests involving these which we saw manifesting in that timeline.

  But his guidance emphasized that the real degree of changes would take place after 98 (as opposed to the beginning of changes in that 58 to 98 period), but again didn't mention the specific year of 2012. 

It's my belief that it's not important who said what will happen when.

We who are presently here in the physical need to pay attention all the time, every day of every year, so we can make the most of our opportunities to evolve.
