The remote is already out, you can buy it from DJI store. Also here's a review I found useful of the remote... I think it's worth it. I bought the fly more combo.
I just got my spark today and took off in my house with beginner mode off due to no gps. Its nice but i wish i had the remote controller. I also wish my mavic remote worked with it. I will try out the dji goggles with it tomorrow.
