Haha cheers man. When it comes to predictions I am almost always conservative as I'd rather err on the side of caution.
On that I would say I sit similar (may even be a reason why people think I'm hating when putting down some predictions).
I hoped and thought there were a small chance PS4 could achieve PS2 numbers (very very very slim chances) but my predictions on the start of the gen were probably around 100-110M on the safe side and 130M as upper limit.
