Will older devices get KitKat updates as well?

A day after we spoke with Tinno and revealed that MyPhone is readying their KitKat update, Cherry Mobile has posted a teaser KitKat update video for two of its smartphones, the Cosmos Z2 and the Omega Spectrum. On the short video, the company demoes the two phones which apparently already received KitKat updates. This confirms that at least two of CM’s devices will be getting KitKat updates, but this begs the question: will the brand be rolling out the update across its entire line, or will the update be concentrated on recently announced products? Hopefully it will be the former rather than the latter.
