It's a pretty good list.
My list would remove Gamedec and Colony Ship. Gamedec doesn't look that interesting to me and I don't like the idea of a virtual world in a rpg. Colony Ship has sharp and good isometric graphics, but I don't like games that are designed with high difficulty as a focus, and that is the philosophy of the developer behind it.
I would put Forsaken Realms: Exodus Rising as probably my most anticipated at this point. (but with "Encased" very close and competitive for the top spot)
I really like the various video updates that the developer has done and the graphics and atmosphere look excellent, especially the fantasy world design. If you can get a high class, believable fantasy world accomplished in a rpg then that goes a long way in terms of game appeal, and Forsaken Realms seems to have that well in hand.
Encased is a game I have been investigating lately, and I think it does look very promising. I also like the science fiction setting and the world looks interesting and highly detailed, as an isometric rpg should be. But it may not be fully ready to be released by the fall of this year, so one to keep an eye on until fully polished and patched up. That said, it does look like they have the basics of a classical style isometric rpg down pat and it looks very good to me.
Pathfinder: Wrath of the Righteous -- I join the anticipation of many here for this one. I have been playing Pathfinder: Kingmaker lately, and its a very fine game, probably the closest to a Baldur's Gate style rpg that has come out since. I definitely am looking forward to what they do next in the sequel, and I think the concept of being an Angel/Demon/Undead Lich as three of the main character background choices is intriguing for sure.
Dark Envoy does look interesting, with a great dark fantasy/science fiction art style. That said, it does appear to be more of a hack and slash style action rpg, although a very pretty and interesting mixture of styles as already noted. But because of the action rpg type focus, it goes into the lower number 4 spot on my list.
I would add Fallout: Miami to round out my list. I recently returned to playing Fallout 3, and very much enjoying it, and that gives me more anticipation for this game with an intriguing Miami as a different and novel city and setting in the Fallout Universe.
