Keep all your camera gear...
but consider putting a Nokia 808 PureView in your pocket as your carry around camera and phone.
A 41mp camera phone shouldn't be overlooked by any serious photographer. It won't best any of your serious gear, but you'll be glad you've got it when you don't have your go to camera with you.
