Asus sent out press invites recently for a May 18th event to announce the Zenfone 2's release in the United States. That's obviously great news because nobody was sure the device would hit North America anytime soon after it only expanded to Taiwan a few weeks ago. It originally launched in China. I'm a lot more excited for the device now that I know I'll be able to get my hands on it. The 4GB of RAM is just too attractive an option to ignore.
