Oh my god!!!!! LEARN TO USE THE SEARCH FUNCTION OR GOOGLE. Seriously, this questions gets asked litterally a thousand times on the web every day, how hard can it be to just do a search for it before asking it. No one knows when the next update will be and frankly no one really cares. You won't get any real answer here. The update may be in a month or in a year or never at all.
You sell "Web Services" yet you don't now about the frequency of updates?? That's a scary though..you should switch careers fast
