As long as the old 4:3 projector in our main conference room holds up,
we won't go out of our way to replace it. In one of our smaller conference
rooms, we've gone with a 16:10 projector which can handle 720p HDTV directly
and scales the higher-def signals, and that has worked out fine so far.
In another location, a software upgrade for some specialized presentation
software used there dropped its support for 4:3 output, so we replaced the
projector with a wide aspect ratio model.
Using an existing screen with the wide aspect ratio projector means that
the overall image will be smaller, but in our two cases, that has not been
a problem. In both cases, when the 4:3 view was stretched to fill the
screen, the lower edge of the image became a blinding hazard for people in
typical viewing positions who happened to look behind them to see if that
was their heads' shadows at the bottom of the screen. Now the lower edge
is somewhat higher without having to narrow the overall view down, and only
the extremely tall are at risk.
