I've been thinking about this more over the last few days and although iPhones have an annual upgrade cycle, all things are pointing towards iPad's moving to a longer update cycle seeing as sales are dwindling and there seems to be a much longer upgrade cycle to iPads. We are starting to see a saturation point where household have multiple tablets and don't buy into new hardware annually. I do wonder if the Apple Watch is going to be similar to this.
Now looking back at the history of the Apple Watch; it was announced in September 2014 but didn't actually release until the end of April 2015. I am still unsure exactly where in the world it isn't available yet, but it's only been a matter of a month or two since it's been readily available worldwide. We are 6 months into the v1 product life. Can I see v2.0 being released in Spring 2016? Certainly not, seeing as we've just seen additions to the line with a Gold & Rose Gold Aluminium Sport. Will v2.0 be released in Autumn 2016? Now that's more likely.
Now lets go back and talk about product lifecycles and update cycles. Apple make most of their money off of sales of iPhones. We are seeing sales go down with iPads and looking at the last few Autumn Events from Apple where in 2014, the iPad Mini wasn't updated really at all.....just a fingerprint sensor from v2 to v3. Now in 2015, the iPad Air wasn't updated at all. Apple decided to introduce the iPad Pro instead. And what happened to the October iPad Event? We were getting used to that over the last few years.
Here's a thought. Keep the Autumn Event for iPhones and make an alternating Spring Event for iPads/Apple Watch one year and Mac's the next. We have started to see the transition to this over the last 12 months, but maybe, just maybe it could look like this:
Spring 2016:
New MacBook's
Bonus annoucement of iPad Air 3
Autumn 2016:
iPhone 7
AppleTV announcements
Spring 2017:
Apple Watch v2.0
New iPads (inc New iPad Pro)
Autumn 2017:
iPhone 7s
Spring 2018:
New MacBook's
By moving to this new scheduling, they are splitting the year up with each evet 6 months apart. And of course we have WWDC in June/July right in the middle.
This gives Apple more time to develop new technologies for both iPads and Apple Watches and then the jump up from the previous version looks better to the standard consumer.
Oh and one last thing...you asked, should you buy a Watch...it's up to you? If we are going to wait until Autumn 2016 at least until v2.0, then you are better just buying now and getting the use of it, although I would suggest just go for the entry models as the pricepoint of SS it too high if it does in fact get updated in 6-8 months.
