disagree but for different reasons. People who shelled out $40USD+ for CGFX4 shouldn't be shafted with no future upgrades. I mean if you pay good money for a RTG system you shouldn't be left out in the cold.
But they're not. They'll be able to go and buy MorphOS and use CGX5 on that, if they like. In fact, I'm sure CGX5 integrated into MorphOS will be very nice.
However, native AOS4 RTG would be much better than CGX5 patched-on to AOS4, for the simple reason that AOS4 RTG would be built into the graphics libraries. This is how it should be, and should have been in 1994 :-)
Also, people who bought CGX4 got just what they paid for, CGX4. They shouldn't expect to get CGX5 thrown in.
