I don't know what to comment here exactly, but the point was that obviously dual cameras systems are becoming a mainstream from now on. And while Apple will be playing their favorite game of hardware crippling "oh, we're reserving that feature for the most expensive iPhone Plus Mega Pro and maybe we'll rollout it to other models in 3-4 years" other manufacturers will make leaps leaving Apple behind. If Huawei could make something so quickly and looking decent then others like Samsung, HTC, Xiaomi or whoever is the king in China tonight will make it even better and pretty soon.
Huawei needed just a few months since the rumors of Apple using two cameras in their phones to come up with something real. And I'm sure that insider info was the key factor behind those phones. Apple will release it (and again a single model of iPhone Pro) this autumn. It has to move faster. Once they switched to yearly upgrades of OS now they probably need to do the same for iPhones. It's impossible for Apple to keep new features/product secret anymore and be ahead of competition. So if they can't keep it secret then at least they should release it faster.
I don't know if releasing iPhones more often is a good idea.
People are already complaining that Apple's product lines are "crowded" and/or "confusing"
Companies like Huawei, Samsung, Xiaomi have 30-40 models at any given time. Apple doesn't.
And if you think EVERY iPhone should have EVERY feature... no one else is doing that.
Huawei just released 2 models with dual-cameras... but that's not gonna trickle down to their other 33 models.
It's OK to have a flagship with flagship features... which is what the Huawei P9 series represents. But their Y-series or G-series are entry-level or mid-range or whatever. Those won't get every feature. Even Huawei wants to offer the ability up upsell people to a better, more expensive model.
Again... Huawei has tons of models... while Apple only has a few models. It's different philosophies.
BTW... Huawei announced the P8 in April 2015. They announced the P9 today... one year later. Seems they are on a one-year cycle too
