Despite the previous announcement at the Ubuntu Wiki, that said
Martin Pitt announces the date to switch Ubuntu Vivid to boot with systemd instead of upstart as Monday, March 9th. He says that the switch will affect the desktop, server, cloud, all flavors but not Ubuntu Touch, and that if there are too many regressions there is a simple upload to revert to upstart.
regarding Lubuntu, the Ubuntu Wiki now reports
LXQt is still in development, so Vivid Vervet [(*buntu 15.04, slated for release in April)] is another bug fix release. A late regression in the desktop installer for 32 bit means there is no Desktop installer for this milestone but it does not affect the alternate installer. Systemd is not the default init system.
LXQt is a light-ish desktop environment built with the Qt toolkit usually associated with KDE-compatible apps.
This announcement indicates that, for the time being, Lubuntu will be sticking with LXDE (Lightweight X11 Desktop Environment) built with the GTK+ toolkit usually associated with GNOME-compatible apps.
Upstart will remain the init system for Lubuntu for now.

Here on SN some users have responded to those criticisms by saying that only the quality of the code matters, not the project's presentation, but sadly in the real world we live in, a presentation that doesn't draw such scorn does matter for getting a critical mass.
A working distribution will attract people who can work on the presentation. Distracting developers with presentation or just organizing the presentation effort just delays the point where they will have a healthy pool of people who can work on presentation. You do not paint the walls before the foundation, frame, floor, or ceiling has been put in place, would you? You might if you were a Silicon Valley startup, but there are many reasons why a large percentage of those companies fail. Making the place look good before having a working product is one of those reasons.
