The cancellation of UltraSparc V is probably a good thing for everyone. US V was to be a new design, not fully compatible with the old ones, but instead leaning towards Itanic. This is good, mainly because it means that they will continue to focus on Sparc compatible chips. This means more stable hardware for us. Also this means that they will continue the focus towards multithread/multicore chips - which are terrific for server usage
This is totally talking out of your ass.... All Sparc chips have to be Sparc V9 compatible. This means that they run all of the Sparc instructions, you know... COMPATIBLE. And comparing it to Itanic? Maybe if it was VLIW, but nope.
They were doomed the moment Compaq got a hold of them. Intel was just a pallbearer....
