My translation of the cited article: "... the new time zone will come into effect at two o'clock on the first Sunday of February, when we will have to advance the clock one hour from its current time, ... "Federal deputy Lizbeth Gamboa Song stated that a new change for the month of April is not considered as yet, given that only the State will advance to summer time. "Nevertheless, the deputy noted that Summer Time has applied in Mexico since 1996, to which all entities of the federation adhere, advancing their clocks one hour. In addition, she noted that it is yet unknown whether Quintana Roo will participate in a further change, but if so, the authorities will officially publish that fact in due time." My Spanish is not native level, but I think the article makes it clear that the decision about DST for Quintana Roo has not yet been made.

The Mexican state of Quintana Roo will likely change to EST in 2015, by not going back from DST in October 2015. Its a bit unclear if they will still observe DST the years after.
According to this source, Quintana Roo will change to EST as soon as 1 February 2015 at 2am: http://sipse.com/novedades/confirman-aplicacion-de-nueva- zona-horaria-para-quintana-roo-132331.html
Through Google Translate, it says "According to the authorities, the term of the new time zone start at two o'clock on the first Sunday of February, when we brought forward one hour actual[?] hours, so the clock will be three o'clock."
Also, the new zone will not use DST.
