2.0 is available now Splunk for FireEye 2.0
you need to ask a question on the existing app and the owner will respond:

No these are old . There is a new version (2.0) that is soon to be released.
Then it sounds like it is either still on developers desk or somewhere in Splunk's "approval process" waiting to be published at splunkbase. Be patient ... 🙂
