The big wait going on right now, other than waiting for KScope and Collaborate, is for release 188.8.131.52. This huge release was first scheduled by the end of 2014, but apparently there's more work to be done. With HFM, there are major changes, like the use of Linux instead of Microsoft Windows for the application server, so I'd rather have a delay now versus delays when trying to use the software and it doesn't work.
In the meantime, take a look at the two conferences mentioned above. They both have worthwhile content and are great for catching up with news and techniques for the Oracle EPM suite.
Collaborate - collaborate15.com - April - Las Vegas, NV
KScope - kscope15.com - June - Hollywood, FL
