The interview seems to confirm one particular point which many people had been wondering about: the Next Gen N-Gage games will not use the N95 and N93 3D acceleration hardware to begin with. However, Ollila does imply that the 3D hardware will get used once it becomes more common.
It's worth reminding ourselves that you don't need 3D hardware to run a game in 3D, the original PlayStation had no 3D hardware yet its biggest hits were good-looking 3D games like Tomb Raider and Metal Gear Solid. The only thing 3D hardware does is allow greater frame rates using more detailed 3D models, but this is icing on the cake rather than the cake itself.
Waiting for 3D chips to become more common in phones makes a lot of sense because this is what PC game publishers did with PC hardware, and the N-Gage platform is much more similar to PCs than to consoles. There's such a variety of N-Gage compatible hardware out there already, with new compatible phones due to be announced several times a year for the foreseeable future.
Hopefully though we'll soon see some N-Gage games which have a graphically enhanced mode for phones with the 3D acceleration hardware, and a normal mode for phones without it. This is how PC games handled the transition from software 3D graphics to hardware 3D graphics.
Incidentally, All About N-Gage and All About Symbian also did an in-depth audio interview with Dr Ollila which you can hear on AAN's YouTube channel (it's split into two parts to comply with YouTube's 10 minute limit):
