Sony Android devices like the Xperia S and Tablet P may well be PlayStation Certified, but you wouldn't necessarily know it from looking at the meagre selection of content available. While the promise of PlayStation Suite seems yet to materialise, Sony is at least making efforts towards it today by announcing that the SDK for the platform will go into open beta next month. This will hopefully bring a range of new, original content to PlayStation Certified devices, going beyond the smattering of PSOne games we've been limited to until now. Later this year the official SDK will be released for an annual fee of $99, giving developers the opportunity to sell their content through the PlayStation Store on mobiles and probably the PS Vita. Sony also pledged to roll out more content across the service this year, and promote PlayStation Suite more heavily on the store.
