On the Odyssey I think it's plausible the bridge could be that big. It seems decent to me, but not altogether impressive. However, I rarely visit the bridge. Then again, I probably won't even be using the Odyssey so it's sort of a moot point either way to me.
As someone noted in another thread, one of Roddenberry's design mandates only broken in Generations was that all Enterprise bridges be the same width regardless of ship size.
If they don't have a new bridge done for the Oddesy, then I'm going to hope that the Delta, Wanderer, and Explorer bridges being available for it. Although the Delta is color scheme is awful, the style of the bridge is nice. It has a few flaws but still. A little touch up work and these could really be very nice!
