they will keep them coming. the only costs they have is to pay somebody to make the operations manuel ( a couple hours of labor at the most) make server space for it, and use bandwidth.
like a previous poster said. they won't look lose money unless the game doesn't sell at all.
EDIT: the reson i think there were no vc games added lately is the recent glut of wiiware games coming out (including some fairly big ones, like monkey island, bust a move plus, and my life as a darklord.)
come try out the computer game i've been working on for my high school senior project, titled sling ball. http://vgchartz.com/forum/thread.php?id=76669&page=1
you can view a few screenshots from the game in my photo album here; http://www.vgchartz.com/photos/album.php?album=2312
