The experts and researchers are looking at the new possibilities with Mayan or Maya calendar. There are many news sources which are pointing to news of groups of researchers traveling to Mexico to find new evidences and talk to the people who are descendants of Mayans. Researchers are interested to know what Maya people have to say about the so called doomsday theories.
2012 movie did not point anything particular in common to the widespread scientific norms. The movie just had a small section which points to the Mayan calendar which ends its cycle in 2012. Largely the movies and other popular sites over internet are not trying to explain anything from the logical point of views. You would find many sites and experts who do good job with explanations for conspiracy theories but there is no trace of realism or science.
Many so-called experts choose to mix bad science and the mythology together to weave the web of confused theories to prove their point. It may be in their interest to do so. One thing is very much interesting about these experts is that they do not reveal their names. Many such experts are having no names but still contribute to the theories for 2012 doomsday.
There are many sites which are 2012 centric but look at the stuff they post there. The popular things posted on many sites include links to 2012 movie which can be watched online. Why a site dealing with 2012 has to post link to movie 2012 and turn itself as entertainment portal. Many 2012 related sites also have 2012 trailer posted online either in the forms of the links or hosted version. This is beyond logical understanding to see what the 2012 related sites are trying to explain with the link for 2012 trailer.
As written earlier the rumor crows are not making many noises for 2012 end these days. It is expected that 2010 will remain so, you may see sometimes, no or very few news articles appearing in many sites. Many sites related to 2012, have not been updated for very long time now. Well, if so called experts think that 2012 end has been deferred or it is not important now, it points to the fact that many of such sites were driven by the hype of movie.
World in 2012 is not going to look much different from now.
