There are updates planned for the game (including harder difficulty modes, and new skills, like dual wielding).
There was a crash issue around Silverglen fixed shortly after release, etc, depending on what version you 'demoed'.
The Cyseal map is about a quarter to third of the game. Playtime is about 80 to 100+ hours (depends on difficulty and playstyle, etc).
I liked Dragon Commander, FWIW, not generally playing RTS games (since I suck at them, usually; with Dragon Commander I worked my way up to playing on normal difficulty, but then, for lack of time, didn't play enough to get very good at that level). I actually bought a couple more RTS games since then, that I wouldn't have even looked at before, though they are still sitting in my backlog.
