Yea, that is true, I'd just want them all on dvd even with no extra features, but features are always good anyway... Besides if you play a video like 10 times it will start breaking down, that's why they need it on dvd which will last forever... The company probably thinks that if the new tmnt does good the fans will be seeking the older one, but I personally think that you can't really compare the 2 at all with over a decade in time difference. I bet fans will still want the old ones even if the new ones flop, but that's just me...Bah..Only time will tell...
Regardless, watch the new one anyway, because that is what the company wants to do good!
