There were several announcements in 2004 and early 2005 that implicated that several manufacturers would be building CRTs with slimmer electron guns. See here and here. What happened to those? I haven't seen ANY announcements about their release in the last year or so. Were they abandoned in favor of SED development? Seemed like the ideal solution, especially since SED, FED, OLED all seem to be...well...not happening any time soon.
