I skimmed the Wikipedia article and didn't notice any mention of removing the initialism. I did find a note that the original language standard did define the "es queue el" pronunciation, but since no one is standards compliant anyway, I think I'll still stick with "sequel" (:
Someone there also keeps saying that the second reference on the article explicitly says it's not an acronym, but the current second source explicitly says it is, so... ¯\_(ツ)_/¯
