King's Bounty - E3 Previews @ IGN, GameSpot

A couple of previews have rolled in for King's Bounty, although both articles are fairly short.  Here's IGN:

Battles are all turn based and play out on a grid covered in hexagons. Depending upon the fight, logs may block out squares and create a bit of protection or gold may be scattered around for the ambitious. Environmental distractions aside, King's Bounty combat is all about moving and attacking. Archers have the range, knights have the strength, but the summoners are where it's at. We saw a reaper cast a cloud of death and a poisonous creature summon that was most effective, so much so that he surprised our 1C rep demoing the game.

...and GameSpot:

You'll be able to select either a paladin, magician, or knight to start with, and you'll also be able to distribute limited attribute points to customize your character a bit. Our demo began with us in control of a knight atop a horse. The overworld map was viewed from an almost top-down perspective and had a medieval setting. There will be other levels, though other than a castle with a moat of lava we didn't get a chance to check them out. You won't be capturing castles in King's Bounty, nor will you be given mission objectives to complete a scenario. Instead, you're able to roam free and get quests by talking to people throughout the land. You will be able to visit castles, where you can spend your hard-earned money on new party members, items, and supplies.
