You would rather not know how the cards will perform, and just have people talking crap?
If they aren't able to have the cards out, surely it's better to have information to enable people to make a purchasing decision when they know the cards are coming?
I never got the problem with paper launches, as long as they aren't too far in advance.

Here's a Sandy Bridge preview from August 2010.
The chips arrived in January. That's a long time. Did you have a problem with it?
For most people on these forums, they are debating the performance of the new AMD chips, how they will perform relative to the old ones etc.
Many people are saying that X (new card) will be slower than Y (current card), so Y is a good purchase since we know the price that X will be.
Well we don't know how it will perform, but if we do know, people can either choose to buy the alternative now, or buy the new card when it does come out.
IMO there's nothing wrong with paper launches if they are very clear about when cards will arrive, and if cards do arrive on time.
I'd personally LOVE if NV paper launched their next gen cards right after AMD launched their 7000 series, I'm aiming to buy a new graphics card when Ivybridge comes out, but I could hold out on my HD6850 for a while if the future holds something that's better value, but if I don't know how future products will perform, should I wait and hope, or just bite the bullet?
