For those of you who have come here searching for info on Sheemie's Tale. (as this is the first link that shows on Google)
Wikipedia now says:
"Sheemie's Tale, a one-shot that's meant to serve as an interlude between The Journey Begins and The Little Sisters of Eluria, was originally scheduled for publication in November 2010, then postponed to January 26, 2011, and has since been indefinitely put on hiatus"
Hope this helps people searching for this issue as it has taken me -over a year- to discover this reality and cross this issue off my want list.
