I have recently bought arkham horror (base game) and have a few games under my belt. I would like to purchase the expansions in order so that means CotDP and Dunwich Horror next. Both of these are unavailable at my local store . I notice on the upcoming page both of these are down for 2013 reprints. So to my question

Would the reprints have any differences to the older version?

if not then i may as well just pick them up from amazon, but if they do then i guess i can wait til my local store gets the reprints in stock.

The only revised edition we had is Curse of the Dark Pharaoh. The original one is almost impossible to find anywhere. So, I'd say go via Amazon without thinking about it twice
