no, PS3 had a very slow start while PS4 had a record start so using PS3 to base your sales curve on is a really bad idea.
And why did it have such a comeback? Because it dropped to $299. In the same time frame PS4 should be $100 cheaper and of course have more dominant momentum to boot. We'll see though. I just don't see people suddenly buying drastically less PS4's when there's nothing else of any note to really take it's place. Since the X1 isn't picking up that momentum any time soon.
