Yes everything will be wiped. Google automatically backups your calendar, emails, contacts, Wi-Fi passwords, bookmarks for Chrome. However, things like sms messages, pictures, save games, music, ringtones or any other type of files stored on the nexus 4 are not backed up automatically. Make sure to backup those manually by using a third party app or directly coping it to your computer.
