Please be advised that as of December 2013, support for IE10 in EPM products is planned to be introduced in PSU 18.104.22.168.500; which may tentatively be released in Q1 2014. Please note that this is SUBJECT TO CHANGE with regards to date/version in which IE10 will be supported; until we receive full confirmation from development regarding this.
That should be welcome news to a number of organisations who are trying to move forward with their hardware/software but limited by vendor support for newer software. Users should now/soon be able to happily use IE10 and Office 2013.
Obviously 'subject to change' has been fairly well highlighted so don't bet your life on it but we can be quietly hopeful.
