Old school doesn't necessarily equate to sandbox, there were plenty of themeparks around 10+ years ago too. But, to answer your question, hybrid is the future. Themepark is the best way forwards for telling stories as developers need to control everything in order to get the best storytelling experience. Sandbox is the best way forwards for providing player freedom and longevity as it relies much less on developers producing content. So, take the best of both worlds and make a hybrid.
Please do not respond to me, even if I ask you a question, its rhetorical.

I mostly play computer based role playing games along with many other types of games. I don't pay attention to or care whether others try to label the games I play in a positive or negative light. Whether they think that the terms 'theme park', 'old school' or any other label they choose are positive or negative is their opinion. I play games because I enjoy them. I don't play games that I don't enjoy. That is what matters. Not the labels.
The gaming universe has moved along without them.
