Nintendo is having tremendous success with its handheld console, the DS, despite the fact that Sony's PlayStation Portable has been providing intense opposition. Given Nintendo's recent moves, it seems that the company is planning to delve deeper into the casual games arena, engaging Apple in the process.

Accordingly, Nintendo recently filed a patent that will bring the Wii's motion-sensing features to the handheld platform hinting that a new DS SKU is coming soon. More interestingly, analysts have said that a motion-sensitive DS is similar to Apple's motion-based accelerometer-enabled iPhone.

  

Apple has reportedly been preparing its library of games for the iPhone. Engadget.com Editorial Director Peter Rojas commented that "Apple is expected to make a gaming announcement soon by Macworld in January at the latest". AppleInsider.com Editor-In-Chief Kasper Jade added, "I was told that a major game developer was seeded with iPhone [technology] quite some time ago".

Some of you may comment that iPhone is not really a contender because it lacks buttons. But technology expert Seth Porges already has an answer to that, "If people could get over the lack of real buttons, the fact that the screen is multi-touch could be ideal for light gaming".

If all of these turn out to be true, then all we can say is that we are all in for a great war between titans Nintendo and Apple and we hope that the consumers will benefit from this in the end.
