New plot functionality in MathCad Prime 3.0?

I just renewed my subscription to MathCad and although there are some leaks concerning the forthcoming release, still there is very little information regarding plotting enhancements. For example does anyone know if PTC have reinstated gridlines on the graph plots and/or a second independent Y2 axis or can we include a raster image as a background to a plot; say a contour plot on land surface or radiative heat transfer to an object for example? If not then I am afraid I may have wasted my money. Considering the fact that Wolfram is soon to release their cloud version of Mathematica which has engineering unit support also; then MathCad 3, to me at least, seems to be trailing far behind in the technology stakes. If PTC ignores basic functionality then it is certain that it will go the way of the dodo. New Numerical Functions are all well and good but if one cannot interpret the output of functions in a coherent way then in my view the thousand lines of code that precede the answer are somewhat irrelevant particularly when all someone is trying to do is extract the relevant information to a report.
