It is admittedly a bit confusing. Because of the slight feature gap right now and the rather large changes between engine 5.3.2 and engine 6.0, we know that some users may not wish to or may not be able to switch over to V6. Because of that engine V5 is still for sale. That is why you see that comparison chart, to help people decide if V6 is right for them now or not. We have many engine customers with very large and very heavily integrated engine installations and it will take Them time to test, evaluate, and rebuild integration points to the new V6 system. If you take a look at the info on Episode V6 in the Episode encoder section you can gat a good idea of what the new engine is like. Feel free to download the demo version and try it out as well.
