Confusing Information

Hi, I'm a little confused about the newest version of Adobe LiveCycle Designer ES4.  Some are saying this is what I need in order to have Adobe LiveCycle Designer forms work on iPads, others are saying that I need HTML5. 

I thought I read here,http://www.adobe.com/ca/products/livecycle/mobile.html, is that Adobe LiveCycle Designer ES4 will render the file in HTML5 so that the forms could be used on the iPad.

Can someone clarify for me on this?  Do I need to have both Adobe LiveCycle Designer ES4 and HTML5 or will Adobe LiveCycle Designer ES4 work?

Thanks for any information you can provide.
