Predict lifetime sales for Forza 3 and GT5

[mrstickball]

I think that it's important to look at other top PS franchises, and how they've fared on the PS3 before arguing if GT5 can outsell GT4.

A few examples that we currently have:

1. Metal Gear Solid Series:

I. 5.59m
II. 5.58m
III. 4.02m
IV. 3.87m

2. Ratchet & Clank Series:

I. 2.93m
II. 2.42m
III. 2.17m
IV. 1.59m

3. Virtua Fighter Series:

I. 1.07m (Saturn)
II. 1.93m (Saturn)
III. 0.39m (Dreamcast)
IV. 1.71m (PS2)
V. 0.51m

Given the trends, I don't see GT5 getting to GT4 numbers.
