Acer revealed an aggressive new design for its duo of Predator gaming desktops earlier this month, but at IFA today, the company's focusing on powerful portability. Acer's been pretty open about its plan to introduce Predator laptops and a gaming-centric tablet, but until now, details have been sparse. Now, we've got the full skinny, starting with the new Predator 15 and Predator 17 notebooks. If you hadn't guessed already, the main difference between the two is their screen sizes. The Predator 17 sports a 17.3-inch 1080p display, while the smaller model's 15.6-inch screen comes in full HD and 4K options.
