Interpretations of the Maya calendar that the world might end on date 18.104.22.168.0, Dec 21 2012, were often roundly dismissed as having no historical basis and being inconsistent with Maya beliefs. See the wikipedia article for a summary.
The wikipedia article cites the lack of direct evidence for doomsday prophecies for that date and the occasional mentioning of later dates including 22.214.171.124.0 + 10.11.10.5.8 = 126.96.36.199.8 (Oct 21 4772) and a date more than 10^31 years into the future.
However, there may have been different opinions about when the world would end and two dates hardly prove that notions that the world would end on 188.8.131.52.0 would have been seen as ridiculous.
The date of the creation of the current world is written not as 0.0.0.0.0 but as 184.108.40.206.0 (as explained here), which sure as hell indicates that the previous world was destroyed and replaced by the current one on a date 220.127.116.11.0 (in 3114 BCE). Note that according to Maya mythology, the world underwent several cycles of creation and destruction of worlds before the current one. Further, their entire thinking placed great importance on regular cycles.
Is there any reason to believe that they felt the current world would not be destroyed? Is there any strong evidence suggesting that it would last longer than the one before (longer that 18.104.22.168.0)? What are the main arguments for why the end of the world date 22.214.171.124.0, Dec 21 2012, would have been inconsistent with Maya mythology?
Edit/Clarification: I am asking about the classical Maya; those that actually used the long count; the ones that flourished until ca. 900 CE. I am not talking about modern esoteric receptions, adaptations, conspiracy theories, or opinions. I am not even talking about modern descendants of the classical Maya (i.e., contemporary Maya).
I am not suggesting that the world did or could have ended in 2012. I am asking if, from the point of view of the historic classical Maya, it would have been conceivable that the world would end (and the next world would begin) on 126.96.36.199.0 (i.e., in December 2012). And I am asking what historic evidence we have for this.
