I think he means the weight of the intercooler, hoses etc on the 4 Cylinder turbo brings the mass equal to that of the n52 which is naturally aspirated.
On a drive-ability standpoint and efficiency standpoint, I think the new 4 turbo is better than the n52, considering their masses will probably be pretty much similar, but the n52 is an inline 6, which is sooo smooth, and so happy at high rpm.
I love my n54 though.
At the very least, every 4cyl needs a balance shaft to offset vibration, which is one of the reasons the inline6 and the flat6 are so sweet.
