Apple has had a busy year of new product launches already, but there are at least four additional products that reportedly are ready to launch, save for one key holdup: the new Siri.

Siri’s delays are the reason for several MIA Apple products

When you’re a company like Apple that develops the hardware, software, and services that power products, you gain more control over launch timing.

In the pre-Apple silicon era, for example, Macs weren’t updated as often because Apple was beholden to Intel’s chip development timeline.

But even when everything is in-house, a single area of development snags can still hold up product launches.
