Support for BPMN 2.0 is already included in the roadmap. BPEL and BPMN, both for the description and for the execution of business processes, you have the freedom to choose which notation should be used. BPEL is well suited for modeling certain types of processes, and BPMN is well suited for modeling other types of processes, or sometimes you can mix and match within a single composite.
WSO2 BPS executes business processes written using WS-BPEL 2.0, BPEL4WS 1.1, and also supports workflows with human interaction (WS-Human Task 1.1, BPEL4People 1.1).
