Manor and Campos did make it, but not in the form they were in when selected. Both had to be bought out (Campos might have even changed hands twice before the season started, can't remember) before the season started. And only Manor remain in the form of Marussia.
My point being that the FIA selected 3 teams to join F1 based on what form that team was in when they selected them, and not a single one of those made it without requiring substantial extra investment. But then the 2010 team selections were more about political allegiance than actually selecting competent teams they felt would thrive. I mean just look at some of the names not selected, and count how many points those that did have accrued in 4 years...
So basically, I think were all entitled to be rather skeptical about the FIAs ability to select teams
