That being said, does Apple really feel this is going to curb spam and gaming of the AppStore? These same developers will simply pull their existing apps off the store and repost them as brand new builds. Spammers have no morals, it's a joke to think otherwise.
Ultimately I think it's a good move on Apple's part but I don't think it's going to fix the inherent issues with the abundance of useless apps at the expense of hurting indie developers who don't have the margins to afford marketing expenditures. As it stands, publishing an update is one of the best ways to drive sales for indie developers. I wish Apple would segment the store into a) Apple hand-picked and b) everyone else. The featured sections are far too limiting for the number of quality apps that are available.
