Looks like an NDA may have expired, as a few previews of Thief are online today, offering looks at Eidos Montreal's upcoming reboot of the stealth/action series. There are previews covering an unspecified amount of the game on CVG and Polygon, while the previews on Destructoid and Strategy Informer each boast hands-on impressions of the first four hours of the game, which is probably not a coincidence, as the Thief preview on games.on.net says it covers the same span. That last article also includes a seven-minute video with new gameplay footage to accompany their impressions and there's also a preview on Eurogamer with their own gameplay video, which runs nine minutes.
