At the end of march 2002, PS2 stood at 28.68 million. Should that be the benchmark to compare with PS4? Or should it be PS2 sales at the end of march 2001 (10.61 million)?

The PS4 will not hit 28 million by March. No where close. Not sure how you'd really compare it though, since the PS2 launched at least seven months earlier in Japan than in NA or EU.

That was kind of my point. Should it be march 2001 or march 2002 that we use as a benchmark for comparison of their respective sales considering they had a different way of launching the consoles?
