DFC Intelligence analyst David Cole estimates that games for the iPhone and iPod touch will account for 24 per cent of the portable gaming market by 2014, with much of the growth in the market coming from Apple.

"The dedicated portable game systems from companies like Nintendo and Sony are still expected to lead the market, but it appears growth for these devices has peaked," commented Cole.

"The platforms from Apple are expected to be responsible for the bulk of market growth over the next few years."

The portable gaming market is estimated to account for $11.7 billion in sales come 2014.
