I got it and it's quite fun. Suffered from a lack of Australian servers at launch (bastards didn't give us an offical server >_>) but there's now 2 or so fully populated servers.
Quite a good albeit slow game, feeling very different from the orginal Mount and Blade. Animations and uniforms are all extremely well done and it's extremely handsome looking for M&B.
The rockets, cannons, marching bands and constructions all bring much more depth to the game offering a varity of different play styles. It seems there might be a tad of a balance issue with ranker's bayonets, they outclass all other melee weapons in both range and damage. Horsemen, lancers in paticular, seem extremely pointless and can easily be killed by a single ranker with a bayonet.
I found the most fun to be had in playing in a public server where it's pure chaos while playing as a Russian "Partisan" (basically a conscripted serf). Partisans spawn with random collection of "everyday" weapons like hoes, sickles and bottles. Massive amounts of giggles to be had throwing a bottle at someones face, stabbing a pitchfork through his stomach and looting his gun.

I also had the liberty of being in a public line battle hosted by one of the "clans" that owned the server. It's quite fun marching in a line and releasing a deadly volley of death before crouching under an entrenchment and praying to a god you don't believe in that a stray musket-ball doesn't find your head. A full bayonet charge is also a sight to behold.
