While 3DS has been enjoying a significant level of success in Japan in recent weeks, the recently launched Vita is struggling to make significant inroads into the market. It's very early days for Sony's handheld, but reports in Japan suggest that its slow start is already causing problems, and that Nintendo is set to benefit.

According to a report from Japan's Nikkei newspaper written by Kiyoshi Shin, the head of Japan's IGDA — International Game Developers Association — an unnamed source said that "major Japanese companies are canceling all projects intended for the Vita and are changing development to the 3DS".

It's not so long ago that 3DS was having its own disastrous launch period, with a number of high-profile titles being cancelled while in development. Nintendo reversed that trend with a major price-drop and some big-hitting first-party software: whether its rivals Sony can fashion a similar turnaround, or if Vita sales outside of Japan can reverse the trend, will become clear in the coming months.
