Why not? Chrome 4 is still beta, but when it’s final, I hope Chromium 4 code will be used as basis for Dragon. 
Why is t that CD is so slow in giving new en better updates? It took to long to get to .22 and there are still to much of the existing bugs. I can be wrong but this CD is just a rip-off from Google Chrome so what is so difficult that it takes weeks\months to get a new version. ???
