It has a fairly large chance of beating the Wii, life time sales. This is PS we're talking about here, Sony systems have good legs and keep selling well after the Gen is over. The PS4 just needs to be pumping out games soon (only 2-3 noteworthy games at the moment) and maintain healthy sales, something the Wii has horribly failed to do. On the chartz the Wii (last time I checked) is selling in last place which isn't good for the former market leader, and is still behind the PS1 and PS2 despite its earlier sales.
TL;DR: Slow and steady wins the race
