I think most cosmologists think of spatially
unbounded universes when they consider the open
universe scenario (although it is not topologically
required). These would have an infinite number of
galaxies, although I don't think this is widely
remarked on.

Also note the vast expanses in chaotic inflationary
cosmologies, where there are lots of symmetry broken
"bubbles" in a broth of symmetric field
configurations; I don't know if the "base" topology
is unbounded or not in these theories, but I don't
think it matter.
