Okay, I can understand having a movie play in HD, but why all the extra space?
Do we really need 3 more commentaries, more art stills, and other practically useless junk on so called "special editions"?
Are movie makers planning on making 5 hour movies now?
Someone enlighten me. Why do we need something like blue ray for movies?

The reason is that HD movies take up more space than traditional movies. A new format needed because a 2 hour HD movie will NOT fit on a standard DVD. As it is SuperBit DVDs dumped every bit of extra content and only contain the video and audio, nothing more, and even then they can only fit 540p (Standard DVD is 480p).
If they can only fit 540p on a DVD then how will they ever fit a 2 hour 720p or 1080i film. The problem gets even worse when 1080p movies come out, they will require more space yet.
Compression techniques can compensate for some of the size but compression also can degrade the quality.
So yes, new 25g+ Dvd's are and will be needed.
