Ps3 65 Nano/90 Nano Version Ps3's

[ReggaetonSalsero]

I thought the 65 nano started in the metal gear solid 4 ps3 bundle. I was recently told that half of those bundles are 90 nano chip size and the other half 65 nano chip size. He said all of the 2007 metal gear 4 ps3 bundles were all made with the 90 nanochip while the 2008 model metal 4 bundle are the one's that have the 65 nano chip.

Can anyone confirm this? Very important....thanks
