Firm unimpressed with current processor offerings on the market and decides to play the waiting game.
Sony broke up with Ericsson last year in a bid to start war in the smartphone battlefield and take on leaders Apple and Samsung.
The firm debuted its Xperia P and Xperia U phones at the start of MWC, boasting connected device functionality and dual-core processors.
However, quad-core phones are the latest flavour of the month and Stephen Sneeden, product marketing manager for Sony Mobile, opened up about the firm's strategy for joining the quad-core market in an interview with CNET Asia.
He said: "In the second-half of the year [Sony] is moving to the Cortex A15 architecture, which we feel outperforms the current quad-core architecture."
Sneeden continued by saying Sony is likely to release quad-core smartphones in early 2013, when the processing technology matches the battery efficiency.
