Finally, thanks to IGN.com, we get a good look at the promo image for LOST season 6.  I will say that a source told me early on, shortly after Comic Con, that the poster is NOT official art for season 6 but more of an interim piece.  We will see. Certainly it captures what seems to be the general theme of the season, supposedly, which is bringing back all of the much loved characters.

note from me:  is that shannon?!  ugh.  kill me.
