if ps3 doesnt match ps2 with sales will it be called a failure

I'd say if it doesn't hit 80% of PS2 it would be considered an initial failure.

If it hits over 40 million at this point i'd consider it a success.

That's the trick with expectations. They vary over time.

I suppose the initial expectations are the most imortant however. So I mostly agree.
