i think part of the charm behind the bombcasts and the quick looks is their length. i tune in as much for the personalities as for the information, and I get the feeling that if anything was shortened it would take away too much from the personalities and the interaction of Ryan + crew.
And ultimately, the beauty of the format in which both are presented to us is that you can make the duration last as long as you want to: Don't like them droning on about LA Noire for 30 minutes? Skip to the next segment. Don't want to watch an hour and a half quick-look? Well, if you got the gist of it after 20 minutes, then that's all you need.
I could see your argument being a credible concern if everything was a live broadcast that could not be fast-forwarded, paused, and where you couldn't jump around from time-frame to time-frame. But this is not the case. You have all the power you need not to have a 2.5 hr podcast. It's right there in your hand.
I love how Sony realized that there is something to the whole let's-re-sell-you-the-same-game-again-Nintendo-kind-of-way.
I'm not even knocking it. Heck, if I owned a ps3 it would be precisely for the Shadow/Ico HD collection and now the FFX HD version. Hell, I almost bought a system just to play Shadow of the Colossus at a decent frame rate and HD-fied. Go Sony go, learn from the master!
