So you think spending hundreds of millions of dollars to promote WP7 and Lumia "hype" makes sense if you are planning to dumb them both in just 6 months and start all over? All that money just to boost the number of apps?
In my opinion: Nonsense. It absolutely makes no sense.
All that press that they are building now would turn against them and bite WP8 and Nokia in the a**. That bad press would kill the WP8 start and hurt Nokia HARD. It would be such a dumb move for both Microsoft and Nokia that I just can't imagine them doing it. They have been planning this for too long and planning it together from the day 1.
I would also bet my left one that atleast lumias get upgraded. Some way.
If Lumias get updated then every second Windows Phone would HAVE TO since they all have the same processor and GPU. The only difference with Lumias (and really all 2nd Gen Windows Phones) are the screens, cameras, and proprietary software. Some 2nd gens have FFC, some don't. Some have overclocked processors to 1.5 ghz, while others don't. Other than that, Lumia devices are no different than any other 2nd Gen (and, in the general publics eye, worse when it comes to the cameras).
The Focus Flash, Focus S, Titan, and Titan are all in the same category. Even the Lumia 710. If they upgrade the Lumia 800 and 900 there is no reason they couldn't upgrade the other 2nd Gen devices. The problem, again, are the carriers. They don't want people to keep their current devices; they want new and renewed contracts.
I guess I could retract my statement and say all 2nd Gen devices may get updated, but 1st Gen devices forget it for sure. It wouldn't make sense to, as hardly ANYONE (unless they REALLY didn't know what they were buying) has a 1st Gen Windows Phone that is not up and ready to be replaced for another Windows Phone. It would make sense to cut them off, but cutting 2nd Gen devices would be suicide.
My worry is how slow Microsoft is moving, leading me to believe that no one will get the update without new hardware...
