RadeonHD - What Should be Developed Next?

EDIT (2009/05/16): This poll is now closed. Thank you to the 151 voters for participating. Hardware compositing for R5xx chipsets will be developed next based on a majority vote.

With 2D blitter implemented for R5xx chipsets (Radeon X1000 series cards), there are two options for what to do next. The first would be to finish off 2D support for R5xx chipsets by implementing compositing; the other would be to switch to the Radeon 2400 pro PCI card, and implement 2D blitter for R6xx chipsets (Radeon HD 2000 and 3000 series). Full 2D support for both chipset series will be implemented regardless of which route is taken. However, it does change which is done first.

The advantage of continuing with R5xx chipsets, is that implementing compositing would take less time than starting on hardware acceleration for the R6xx chipsets. It would also mean that one set of graphics cards is fully supported. On the other hand, this would mean that users of R6xx based cards would have to wait even longer. Also, AMD have recently dropped support for R5xx based cards from their drivers, indicating that they already see them as obsolete.

Both options require me to implement microcode uploading. R5xx chipsets require the command processor's microcode for 3D operations, whilst R6xx chipsets require the microcode for any GPU operation. While work on this is in progress, I would like to hear what other Amiga users think the next step should be. Please vote in the poll below.
