Amazon is often, OFTEN wrong about release dates when it comes to games. Seriously, ridiculously, and badly wrong.
Also, about books that aren't yet written. (Apparently Song of Ice and Fire book 5 was supposed to be released a couple years ago according to Amazon).
However, I am hoping for a this week release myself, since I packaged the core set *with* the Skavenblight Threat and won't get the former until the latter's released.
The first thing that came to my mind when I read the thread's title was indeed "A dance with dragons".
