So assuming we're talking about the cyberpunk genre and not the specific rpg, I'm not so sure the cp genre is outdated. Perhaps we're simply catching up to it.
Let's see we've got:
pervasive network that interconnects everything? Check.
Corporations that run things and act unethically? Check.
People who work behind the scenes doing dirty wet work and black ops? umm, I don't know, they've been pretty sneaky so far.
As a computer guy, I'd like to see a matrix/grid/net presentation that is somewhat plausible and realistic. From an rpg design standpoint, i'd like the implementation to be one that doesn't drag the game down for hours while the decker does a run that takes 6 seconds game world time
Corporations are often the bad guys because we see the trend now, that businesses are getting more powerful. Extrapolate that to an extreme, and it is the businesses that are running things. It's not communism to fear, it's TacoBell.
Cyberpunk is often presented as a dark themed setting. To support that, the bad guys are always hidden agenda organizations with a mysterious plan. It doesn't have to be a corporation, it can be a government or fruitloop cult (snow crash anybody?).
Plus you've got the recurring theme of technology. It scares us, it enslaves us, it transforms us and releases us.
I don't think the motif of cyberpunk is outdated or inapplicable. Though it may be tired, because we, as a people are getting more depressed about the world around us (beats me, I'm not depressed, I'm happy, I trust the Computer.).
