You make my day, Chris! (I'm using this "you make my day" idiomatic phrase because I'm quite sure it means something like "you make my day happier with this positive news". English is not my primary language so correct me, just in case..).
Yes, you got it right... Unless you were going for the Clint Eastwood approach, in which case "go ahead, make my day" means something like "if you even think about trying to hurt me, I'll hurt you first" :)
Can you anticipate if will we have:
(The following notes are pretty general and apply to the OGL pipeline on all platforms. Some drivers may be less optimized than others, so your mileage may vary.)
- hw accelerated transforms (bitmap, vectors, with translucence support)
images: yes shapes: yes/no (some simple primitives can be accelerated) translucency: yes
- hw accelerated transforms (bitmap, vectors, with translucence support) with bilinear, bicubic filtering.
bilinear: yes bicubic: no
- hw accelerated stroke/fill/paint
strokes: not yet (more work will be done in this area) solid fills: yes texture/gradient paints: yes
- hw accelerated clipping
rectangular clips: yes shape clips: yes
- hw accelerated shapes, glyphs, text
shapes: yes text: yes
- hw accelerated antialiased shapes, glyphs, text
aa shapes: sort of (at least they're faster than the existing pipelines) aa text: yes
The question is how current applications can take advantage from the new pipeline ? Should we take a particular coding approach for pushing apps performace to the top ?
You shouldn't have to change your app to benefit from the OGL pipeline. There are some things (not OGL-specific) that you can do to help speed up your app that are documented in our "2D Performance White Paper": http://java.sun.com/products/java-media/2D/perf_graphics.html
If there are any tweaks that would help your code perform better on the OGL pipeline, we'll include them in an updated version of that white paper.

Don't tell me you didn't expect my "simple" questions....
