I prefer the underestimating predictions to the ridiculousness that was Wii going to sell 300 million back in 2008.
I doubt PS4 will sell 100 million. But if the 360/PS3 install base is relatively static then PS4 taking 40% or more of Xb360's install base could mean PS4 cracking 100 million. But it is interesting that the PS/Xbox install base is trending downwards. PS2+Xb>PS3360. So if that's a real trend then PS4bone170million-->160million? If PS4bone is going to combine to 160 million, which is a 10 million shrink from last gen, then it's not too much of a stretch to see the breakdown being PS4 100 million Xb one 60 million. But I think Xb one is on target to sell less than 50 million (but probably more than 30 million), which would either put combined sales at significantly less than 160 million, or PS4 at significantly more than 100 million.
