Yes, but only being previewed at GDC March 20 - 22. Release is said to be planned for sometime in Q2 2019. However, there’s some posts around from Timo Wildenhain, stating Video Rendering will not be in the initial release and is scheduled for a v10.2 update.
That could mean the second of two planned maintenance updates (10.1 and 10.2) and there’s usually around 4 - 6 weeks between updates…
All of which says, if N10 initial release is in June (its possible.!), you might actually see Video Rendering in Nuendo 10 by around late July - August 2019. Set your expectations there; if it turns out earlier, then its a great big nice surprise.!!
