More Marketing woes for Microsoft. When will they learn.
In 12 months from now, looking back - the cut-off for previous support will be the Nokia->Microsoft Brand change.
i.e.
Microsoft Lumia 735 running Windows, gets support.
Nokia Lumia 735 running Windows Phone doesn't.
Reason: Nokia who? Microsoft is going to want to remove the word Nokia on their support pages ASAP.
What does this mean?
Another Fire Sale of all Microsoft 'Nokia branded' devices, even the just launched 735.
Given Windows Phone 'WP - Work in Progress' is now in transition towards Windows 10, this is starting to feel like the disaster Microsoft had between their 'stepping stone' WP7 -> WP8 transition, where loyal WP7 users were left high and dry, with no upgrade path.
You really have got to be committed to stick with the Microsoft Marketing shambles, this time round. Let's not even mention now defunct current ARM powered devices such as the Windows Surface running Windows RT and Nokia Tablets running Windows RT, dead in the water, pretty much.
