Sun are keeping suspiciously quiet regarding their virtualisation offerings, both present and future, and you know what they say about the quiet ones. There doesn't seem to be a lot of material out there tying the various pieces of their puzzle together, and it's entirely possible this is intended to keep everyone's focus on VMware / Citrix / Microsoft. I hear a little voice... oh, sorry, you too Red Hat.
But check out what's in the pipeline with storage (starting page 13). Holy fuck - did your head just explode too? Or hows about how ALP shapes up against other remote display protocols (we've tested this first hand where I work - over high latency connections, there is _nothing_ in it between ALP and ICA). Put those pieces together with Lustre, Zones, xVM, Ops Center, and Sun Ray, all glued together with Java... and VMware should be shaking in their boots. We may well see the old kings of the datacenter back with a vengeance in the next 12-24 months.
