Having three out of four home consoles sell over a hundred million units, they must be doing something right, good on them.
Although the PS4 being somewhat on the same track as the PS2 is impressive on its own, what's more impressive is that the price point of the PS4 has been quite a bit higher than the PS2's during its lifetime.
Around its sixth anniversary, you could pick up a PS2 for around $130, making it almost eligible for being called an impulse purchase.
The PS4 is rolling towards its sixth anniversary and it will still cost you around $300 when it's not on sale.

PS3 outsold the 360, just not for the first 3/4ths of its lifetime. It caught up and surpassed it near the end. People just remember the first few years of it where it was getting crushed and assume it kept going that way.
And that is with the Xbox360's 1 year head start in terms of sales, go figure.
