Well, the artwork certainly is gorgeous.
The last two Disciples games held my interest for a short time, but that was mostly due to the artwork then, as well.
Reading about this game, the developers, and their current design philosophy, I wouldn't be surprised if this turned out to be quite the little sleeper hit.
It's my hopeful guess that there will be quite a bit more depth, balancing, and detail of units and strategy involved this time around, which the last two sorely lacked.
I am looking forward to it.
