The Power Series will come in two different styles one which is a bit more compact for carrying around and another, somewhat bigger for other times. The bigger will included larger buttons, taller thumbsticks and a more comfortable grip which is better for longer play sessions. The smeller will feature clickable thumbsticks along with smaller buttons and triggers. Both will have the flip-up phone holder as seem in older models of the controllers as well.
Additionally the controllers will feature a ‘Boost System’ which is said to recharge your phone as you game. Though not many details have been released at this time we can look forward to move in the coming days once the full announcement happens during E3.
