Nah, I think it's possible. Even the E3 trailer exceeded my ridiculous expectations.
Putting together a good trailer is one of SE’s strengths. After all, this company highly values amazing visuals and presentation. It’s what they’re known for.. But like with all trailers, they’re intended purpose is to get people excited and interested in a product. They’re supposed to lure you in. However, that doesn’t mean the end product itself will be good. That said, I can't say I'm all too surprised people are excited for it.
My only concern right now is that the game looks like a button masher. Yeah, there are these 'gimmicks' and vertical battles, but we’ll see. As long as it doesn't feel repetitive and it is covered up, then it's all good.
And after so many years in development, I have to wonder if the game will be all it's cracked up to be? Games don't tend to be this good with such a long development time. It screams a 2015 release and if it hits May 2015, that will be 9 years since the E3 2006 announcement.
