You guys think we might see cartridges make a come back? Either way, I don't really mind. As long as loading times are nonexistent or at least kept to a minimum, I'm happy. And media space isn't an issue for me, what I care about is the gameplay. I don't care about rubbish like FMV, voice acting, licensed music, etc. I'm quite happy with the Gamecube's mini-DVDs.
As for memory cards, I don't really like them. For me, it's just something I have to buy seperately and then keep an eye on the remaining space, so I just find them annoying. Besides, they never leave my house so they offer no advantages for me. I prefered the days where the game would just save in it's own cartridge. I don't like dealing with memory cards.
By the way, screw DVD playback. If you want a DVD player, just get one, they're cheap. I don't want Nintendo to increase the console's price because they decided to include DVD playback, which I would never use anyway. I wouldn't want to put any more strain on my console than I have to. Look at the PS2, you got plently of people who have lasers dying on them. I just use my consoles for gaming, nothing else, and that's why they stay in good shape.
