new high-def studio in Nashville, in comes the announcement we've been expecting. TNA will be taping a live iMPACT! event on October 23rd in Las Vegas which it will broadcast in high-definition on Spike TV. When it airs, it'll mark the first ever HDTV broadcast for the sport. We'd say you could go and watch the sweat / blood in person, but maybe it's best to just take this one in from the (HD) sidelines.
