We are currently in the middle of ERPXE 2.0 development.
Version 2.0 of ERPXE will be released as a tar.gz file and as a Virtual Machine Template.
The base for the VM isn't decided yet but we will most likely use CentOS or Debian for the initial release,
We might even release two different virtual machine versions with different OS Base.
That said we will not include the entire ERPXE base into the VM (over 200GB) but there will be an easier way to Add/Remove plugins.
I can't say anymore at the moment just that ERPXE 2.0 will bring a big change to the way PXE is used.
