New HTMLB controls in EP 6.0

Hello people,

I try to find the info in regards to the HTMLB in the EP 6.0. In particularly my client is interested in the new controls, features, and APIs that SAP is planning to have. They are very concern about performance and memory usage issues related to the HTMLB as well as about the SAP plans in regards to HTMLB. Unfortunately the research I made on various SAP sites including sdn.sap.com, etc. did not give any results. In general it looks like there is no additional information about HTMLB except the info in PDK. Please let me know if you have releavant links. Thank you.
