No, that is very unlikely. Shrinking market, shorter cycle, evenly distributed support between xbox/ps and not coming off of the momentum of a dominant market leader will ensure that, not to mention the fluctuation of the market and developr sphere as a whole.
75% + marketshare, monopolized 3rd party support and 14-15 years of sales are a thing of the past, look at how the PS3 is starting to crash (60-70% down yoy), this will also be the case for the PS4 and developing markets follow the trends of matured markets and won't aid it in having a huge life cycle either. Being the market leader won't ensure 150 million sales by default, this is no longer possible with a static product in the fast moving, revisionist consumer electronics market of today.
I'm 100% certain the PS4 will win but I'm equally certain that we will never see anohter PS2 situation; the market simply won't allow it and the conditions would need to be absolutely perfect, the PS2 arrived and thrived in the peak of an old and ongoing development paradigm and at the height of the economy globally and within Sony Corp, the PS4 has launched into the midst of a transitional and evolvement phase of the gaming industry, a console market segment about to suffer a contraction (look at the imploding handheld market) and is fronted by a company with little to no financial muscle to play at price wars or soak any form of losses for any time, and is released in the wake of the worst period in Sony's long history.
There is no way the PS4 will ever dominate or sell like the PS2, even as a market leader; the perfect circumstances are not present for the PS4 and won't be. This is the "Wii is the fastest selling console ever, of course it'll blast past the PS2!" all over again, both are/were equally unrealistic.
