Colin Sebastian of Baird Equity Research has suggested that the Microsoft Xbox 720 and the Sony PlayStation 4 could arrive this fall, costing anything between $350 and $400. According to the source, 'The analyst revealed that during the Consumer Electronics Show last week he spent time "with a number of companies involved in video game development and distribution," who informed him that the next-generation consoles will be "largely built from 'off the shelf' high-end PC components, along with hybrid physical/digital distribution models, enhanced voice controls and motion sensing, and broad multi-media capabilities.'
