Im excited for everying From has to offer, but yes I am also excited about this game in particular. Though I would also be excited if it was Ecco the Dolphin.
I can't really say whether other people will be excited or dissapointed, the internet is a fickle place and I'm sure we'll have plenty of both. All I can give is general advice on going in with an open mind and appreciate things for what they are rather than what they aren't, it becomes hard to be truely dissapointed that way. I know that's a bit of a non answer, but E3 is still a bit out and I can't spill all the beans all at once :)
If you want to know more, please take a look at the other posts ive made over the weekend.
Ok I need a From developed Ecco the Dolphin sequel now.
