Earlier this week we saw that Microsoft job postings hinted development of a Surface tablet successor was likely already underway, and now another set of postings hints at the future of the Xbox platform. The post on Microsoft's Careers website in relation to a marketing position mentions how a bunch of new products will be launched the next 18 months: Windows, Windows Phone, Office, Surface and Xbox.Over the next eighteen months Microsoft will release new versions of all of our most significant products including Windows (Client, Server, Phone and Azure), Office and Xbox, along with completely new offerings like Microsoft Surface. This wave of product launches will define the course of the company for years to come and thus provides an unprecedented opportunity for us to refresh and evolve our strategic brands.Of course this is no definite confirmation that a new Xbox will be available in 2013, as Microsoft earlier this week had to clarify a statement made in relation to the next Xbox being in development - even though it's still rather obvious Microsoft is secretly developing a next-generation console to compete with the Wii U, the next PlayStation and advancements in PC gaming.Documents that were leaked earlier this year in relation to the "Xbox 720" mention a next-generation release for 2013, plus a successor to the Kinect (named Kinect V2 in the documents) is also expected around the same time. A price point for the console is speculated around $299, and there have been several, often conflicting rumors surrounding the hardware.
