That's not going to happen. Netflix is committed to releasing all the episodes at once.
Sure, it's better for viewers because they can watch at their own pace, not forget details, etc, but from a business standpoint, it doesn't really make any sense. They have a guaranteed base of users now and they'd be throwing money out the window by releasing them at once for season 2.
As they should be. Anyways, Netflix stands to gain nothing from staggering the release.
Several of my friends signed up for free trials just to watch season 1- they don't plan on renewing. If it was released on a weekly schedule or something, at least they'd have a few more months in the books.
