Suma posted about v1.09 patch on this BIS forum topic:
What is taking is so long is especially VoN fixes and anticheat measures. Both need quite large scale testing with external (voluntary) testers involved, which makes turnaround time for any changes in both areas quite long.
Still, the patch is progressing quite well and hopefully there will be at least a public beta within a few weeks.
