Yes, so far we only have Zylesea's recent statement on aw.net for possible PowerBook G4 support in 2.8.

> and against.

In Bad Bramstedt in November 2010 it was said by MorphOS Team members that

1. faster R100/R200 3D drivers were supposed to come in 2.8,
2. R300 3D drivers were supposed to come after the faster R100/R200 3D drivers,
3. PowerBook G4 support would definitely not come without R300 3D drivers.

Now do the math.
