Are you asking if it can do things that the PS-CC-hosted ACR plug-in can do, or are you asking if it has support for new cameras?
Elements has always had dumbed-down raw editing capability, with only toning and detail and camera calibration tabs, and those tabs are not where the innovation was in PS-CC-hosted ACR 8.x so I’d expect nothing to change about what sorts of edits you can do in the restricted ACR plug-in hosted by PSE.
PSE13 should be able to be updated to ACR plug-in versions through next May-June timeframe, at least, so new cameras from the fall, winter and spring seasons in the northern hemisphere should be added as they are released. The last ACR update of the summer usually doesn’t make it to PSE, because I’d guess the new PSE version is already in final stages of testing so they don’t want to test it, again, with a new plug-in and delay its release.
The main thing to notice about PSE13 is that support has been dropped for Vista and XP and OS X 10.6.8 and older. This is to make it compatible with similar minimum support for the ACR plug-ins, AND it supports 64-bit Windows so there will be less memory problems when opening multiple photos.
