"After visiting the site it seems that the new Next Gen platform will not be limited to 3d chips or Symbian 9. Its seems pretty likely that the Symbian 8 powerhouse, N70 will also be a part of it."
It won't be limited to 3D chips, the site actually says so.
But I can't see any evidence that they'd go back to Symbian 8.
Nokia recently said there would be about six phones that would support the platform at launch, most of which haven't been released yet (so they're bound to be Symbian 9 because they're new). They also said that even more new models released after the launch next year would also be added to the platform (and they're also bound to be Symbian 9 because they're new).
It's just not worth writing completely separate Symbian 8 versions of the games if there's hardly any Symbian 8 models that support the platform. Symbian 9 is not backwards compatible with Symbian 8, it would take extra work to make two versions of everything. It would also put off third party publishers if they were told that they had to write everything for two separate platforms, and third party support is something that every games platform needs a lot of.
Nokia are still manufacturing and marketing the N70 for the same reason they're supporting their non-Symbian phones, because it's a very popular model which is earning them lots of money. They were still manufacturing the 3310 until last year! 😊 Most people who buy the N70 aren't doing it for the software, most of them probably don't even know what Symbian or S60 are.
The "internet edition" and "music edition" aren't really different to the original versions, they're the same phones doing the same things that the "normal edition" does. It's a marketing trick more than anything else, so that the average person realises that they can use their phone as an ipod or a web browser. Many people don't realise just how powerful phones are nowadays.
By the time the games platform launches in the middle of 2007, the N70 will be two years old, ancient in smartphone terms. Another problem is that the N70 also has a tiny screen resolution, the same as the original N-Gage, whereas most of the new S60 models have resolutions of 320 x 240 or even higher. It would be a pain to support a low resolution when the vast majority of compatible phones have a much higher resolution.
I hope I'm wrong, it would be great to see the games available to virtually anyone with a S60 phone, but it seems very unlikely.
