I think the NES-era (and to a lesser extent SNES-era) will continue to be heavily represented. As you stated, they are simple enough for people to really take them apart, in a large part because the games were actually written in assembly, unlike later eras of gaming. But also, the NES-era games have aged better than earlier games. As much as I love River Raid, it's no Super Mario Bros. Something about on-screen menus (what do you mean I need to hit "reset" to start the game, Atari?), having more than one button, and enough processing power for decent physics.
