Speed improvement in Bryce 5.5 is because they cleaned up some sloppy coding. Studio will not be a part of Bryce. You will be able to launch Studio from Bryce, automatically loading the selected figure. The figure will be tagged so that Studio opens the original (still poseable) figure, not the .obj file. You can then make adjustments to the figure in Studio and re-export it to Bryce, with the .obj in Bryce being updated automatically. Relax, DAZ is trying to save Bryce, not bury it.
