It's absolutely possible. You can use developer's past history and credibility for making games to predict the quality of their next error. If there are any red flags that come up in previews, then you can change that opinion.
I'm certain that the next Persona is going to be fantastic because there's yet to be a bad Persona game. I'm willing to bet that FF15 will also be great because of who is working on it. You obviously can't necessarily review something based on watching it, but there's a reason why I ignore most reviews and just buy what I'm interested in. It works for me far better than reading what journalists have to say.
