does that, somehow or other, explain the video being divided almost two minutes before the "welcome back" dialog came up?

It was stated in the press release that these games are expected to bring new life into the franchise, but I really think that's just Game Freak trying to hype up crap that no one really cares about. They have a tendency to do that, after all. "Hey look, Contests are now called Super Contests and you can dance with the touch screen." "In Heart/Gold, you can get your own Pichu with fucked-up fur just like in the movie." "This special Riolu can get an attack its evolved form already gets, making it a mere novelty that would lose its entire point if it does evolve." And so on... I'm sure there was crap from earlier generations as well, but it's not coming to mind. So overall, I'm not expecting too much from generation 5 in terms of game mechanics. There might be several gimmicks, but I doubt there'll be much that's actually revolutionary.

Just bring on the new Pokemon, new moves, and with any luck fix certain movesets that they apparently dawdled on doing even in spite of Platinum and Heart/Soul's release being perfect chances to do so. I'm hoping those shiny legendary beasts are packing future tutor moves (much like the Regigigas that came out before Platinum). God knows Entei needs that Flare Blitz, and speaking of which [cough]Eeveelution[cough].
