As an after thought; it occured to me that I haven't seen much discussion of the pending content so I'm bumping and hoping others are as keen to see it as I am. I would also like to add my two cents: post release Zenimax Online has continued to support the game with patches to address post-launch issues; in addition to new game content such as Craglorn which is incoming. All the while readying for pending XBOX ONE and PS4 launches.
