Possibly. However, is the CPU the bottleneck? In most cases my N900 is slow, it is due to IO wait, not actual CPU utilisation.

* gaming will be on a different level
Mostly a task for GPU

* smoother GUI transitions
Task for GPU

* better batter usage (in theory, two horses can climb steeper hill than one horse)
But, two horses need twice the food and water than one.

DSLR has the optical capability but mbile is fixed lense.
It's not only the lens optics, the sensor size has a huge impact on SNR.

Comparing Qualcomm to Cortex is like AMD to Intel.
No, it's like comparing AMD to x86. One is a subset of the other. Maybe you mean Qualcomm Snapdragon to TI OMAP?

if N9 doesn't have atleast dual core A9 + 1GB RAM then I don't think Nokia will ever compete in the fast growing mobile era.
A single-core, with higher clock speed then N900, with 512MB or 768MB would probably be enough, depending on the GPU (see some of the tweets about polygon rendering speed of N9, it is comparable to lower-end gaming devices). I doubt many users will see benefit of 1GB over 768MB on a mobile phone.

Also having 12MP camera is a bonus when recording video in high resolution and densing the pixel to 1080p is better than 5mp, eg. N8 took great videos quality.
If you want good video for least cost, a lower resolution sensor with less noise would result in less image processing overhead (but, this should be done by the DSP in most cases, not the CPU).
