Since you say you're a journalism student, if you're doing this for a journalism assignment you should definitely make calls and conduct the interviews. I have an MA in journalism (University of Missouri-Columbia), and while that was in the pre-Internet days, we had to conduct interviews. Only by talking to someone can you really follow up on off-hand comments, or pick up on pauses, or probe for more information.
And some of your questions have built-in assumptions that may be incorrect. You're assuming that developers have confidence in this market, to use your language. I can think of half a dozen reasons why development projects are continuing; many have nothing to do with whether the developer has confidence in the market.
Hope that helps.
