- support for a larger number of virtual CPUs per guest in the
 hypervisor (tools and pv-ops kernel are lagging afaict)
- support for a larger number of interrupt sources (i.e. big machines)
- support for bigger (potentially sparse) memory configurations

Developers:
I have started work on our Xen 4.0 Datasheet which will allow 
customers/prospects/users to learn about the newest hypervisor offering from 
Xen.org. I currently have the following list in the document:
* Kernel Upgrade
o PVOps Dom0 Kernel based on Linux (version number)
* Blktap2
o Support VHD format
o Snapshot virtual disks
o Command-line invocation method
* High Availability (Project Remus & Kemari)
o Up to date replica of a VM on backup server
* Netchannel2
o Lazy copy in guest
o Support multi-queue NIC, Smart NIC, SR-IOV
* Page Sharing
o VMs share identical pages in memory
* Libxenlight
o High level operations shared across all Xen toolstacks
* Support for Virtualization-aware Applications
* Transcendent Memory - RAM utilization capabilities
* Multi-function PCI pass-through
Please let me know if I missed a feature or if I need to make any changes to 
this list. Thanks.
