VMFS3 does not change with the release of vSphere 4.0

That mean each VM need to upgrade their virtual hardware?

So, will ESX 3.5U4 hosts be able to access and use datastores formatted by ESX4 Hosts with VMFS 3.33 without problems or drawbacks? If not, will VMware quickly provide a patch for ESX 3.5 that adds support or something like that?

In my lab, I can access the same LUN from both VI3.5U4 and vSphere4.0. I'm even running live VMs simultaneously from both platforms on the same shared LUNs. I have to mention that I'm using vSphere 4.0 RC however.

There is no issue, it is like running 3.x.x hosts against 3.5 formatted VMFS. it just works

To use new vSphere features (like FT or hardware hot add) yes.

But you can still play old VM format.
