Yes, there was - there's a (low) qualiy video here:

Not much at all though - really only that 8 seconds, appearently, which showed Cherrygrove again, which we've seen before, and the Rival's battle sprite again. Only bit new is the neat 'VS!' animation that occured before the battle, really...
Oh well, news may be just drying up now until the release/close to it, although there is reportedly a decent chance of an interview with a Pokemongame creator on HG/SS on the show next week.
