Welcome at this forum, but I think we should not disturb GWX creators with their work.
Members of this forum don't know more about GWX than is written here:

As is said there:
Please respect the time and effort the GWX team members are putting into this release by not inquiring about its release date. Our guys have been working their tails off for WEEKS and need no more pressure than they already put on themselves.
It's very difficult, but we should wait patiently
