BW doesn't offer numerical projections, but they do say:
"On Feb. 17, Intel Corp. Chief Executive Craig R. Barrett sank Itanium's last hopes for gaining broad success. He announced that Intel will reconfigure its own 32-bit chips, the Xeon for servers and the Pentium 4 for desktops, so that by midyear they also will be able to process 64-bit software. With Intel throwing its weight behind other products that can handle 64-bit applications, Itanium looks doomed to niche status."
