Questor, that's exactly his point. P4 is not P5. P5 can do a bunch of things that P4 can not do without adding extra programs. It is apples and pears, and that's exactly his point. If I was comparing Lightwave 7 to Lightwave 1.0 I wouldn't limit myself in LW7 to only the features that LW1 had. I would be trying to show that LW7 is more advanced and better, so would show what IT can do, not that it can still do what LW1 did. This is the same. He's showing that P5 has a bunch of new features that P4 just doesn't have.
