I think you need to slow yourself down. When, and if, another easter egg tethering app makes it into the app store, it will be very prevalent across the tech news websites. And it being a holiday will make no difference. Devs submit their apps to Apple, and Apple will post them whenever they have finished qualifying them.
Besides, I'm not sure how many have ever made it into the app store(I can only remember three specifically). So don't get your hopes up.
