Not in the short run. There is obviously no shortage of developers (who are willing the use the mandated languages) or apps. But I do think they may regret this eventually.
By excluding languages like Scheme, and many others, they are excluding developers who prefer these languages. One could argue that these developers are among the smarter and more creative ones. So, when competitors get their act together, and come out with a similar device that doesn't suck, and an app store alternative that does not have these restrictions, then this is where such developers will go.
Essentially, they're providing the competition with a sizable pool of (often disgruntled) developers. There is no real competition right now, but they're making it more likely that there will be, in a year or two.
As much as I'd like to agree with you, that is simply not going to happen. Do you seriously think companies/developers like EA, Cultured Code, Omni Group etc are going to leave the app store just because apps written in Scheme or Actionscript or .Net are not welcome on the app store?
Again, as much as I'd like to agree with you, none of the prominent app developers are going to be leaving anytime soon. And, as for people who make Farting apps, they probably wont care anyways because use Objective-C or Actionscript, the apps are rather simple anyways. The efficiency of writing code probably wont matter to them.
Expected. There's a three tier system- Tier A partners like EA, Tier B developers that are preferred by Apple, like Cultured Code, Omni, and TapTapTap, and Tier C developers, who Apple doesn't do anything special for. Kick ass for a sustained period of time and you can get into Tier B, be a multi-billion dollar company and you're Tier A.
Awesome thing is, though, that you can reasonably compete as a Tier C developer with Tier B and Tier A developers, it's just that they get a head start with being featured. That's surmountable, so it's not a big deal.
This is a mistaken claim. Naughty Dog, for example, uses a precompilation phase in their games involving Lisp that builds into machine and graphics code. Most games, too, have a dynamic runtime in the form of a customized scripting engine in their game, tailored to the needs of their game. Sometimes this is done with a pre-existing language like Lua, sometimes it's built from scratch, like UnrealScript (Unreal1 - 3 engines). All of these are now banned.

Anyway, just my $0.99... :-)
