According to a Japanese Dr Serkan Toto a Japanese publication to the Nikkei reports Nintendo will release recorded game clips and playable demos on mobile devices intended to promote its games.Dont expect to see Mario or any other of Nintendo's large IP on your handset to play for hours on end but you maybe getting a free level or a timed single play through for a few mins.
Nintendo would do well to start looking at other platforms for its IP like Sony is, Nintendo risk becoming stuck like Sega did before they jumped into the software business full time, their share price and Q4 earnings are tanking. So whats to give first ?!
