Fair enough.
I'm sure Battlefront, like any other conscientious business, appreciates constructive feedback. To keep things in perspective though, if the preorders were to be released well ahead of the the 19th, one would question the rationale behind publicizing a release date in the first place.
My experience with preorders has been that you typically benefit by securing a popular title on release day, receive a little something extra (if only token) and perhaps save a little money in the process. With ToW, the preorder nets you a physical copy, allows you to download a digital copy while further discounting $10.00 from the retail price. Oh, and as an added perk; the digital download will open a day or so prior to the official release day! Seems like a decent deal from my angle.
If it makes you feel any better, think of the official release day as the 26th instead of the 19th.
