I was reading http://virtualgeek.typepad.com/virtual_geek/2008/08/our-vmware-cent.html#more Best blogs on vmware and EMC
a smaller number of hosts generating a LOT more I/O More VM per host more I/O
will need faster transports (10GbE), and where a slower transport is used (1GbE) we need higher port density I think Infini Band
end-to-end QoS mechanisms since it will be a unified fabric
you will need dynamic flexibility to add/remove/change all elements on the fly, non-disruptively. High redudant hardware components
Certain core features, which were the battleground of yesterday become a given (virtual provisioning, dedupe, writeable snapshots, dynamic and auto provisioning, performance auto-tuning, etc) – every vendor has their own spin on these things, and they do all have a place in the VMware pantheon – customers should look at them and decide on their merits. We can do them all, and we each think we do them better than others. Most customers I talk to don’t even leverage what they already have 
On reading above blog i can feel next generation would one big box of VMWARE with all stuff similiar like Mainframe, we will be called ESXFrame
