Yeah, I like the new concept of concealed weaponry, with big weapons replaced by the counter/take system. It seemed a little odd in the first AC that you could pose as a 'monk' for disguise while you're carrying like 15 throwing knives, a huge sword, and a short blade on your back, all in clear sight. Must have had some badass monks back in the third crusade (Technically, the Teutonic Knights [Also known as the Templars] were all monks, but eh).The combat in the original AC was very fluid and fun with the whole context-sensitive fighting, but it didn't seem as hell-crazy as it should be (anyone who's played Lugaru knows how fucked up it is when you've got four guys on you
) for the larger battles. The new things like poisoned blades and all the cunning are really showing how Ezio favors brains over brawn, as opposed to Altair's "HULK SMASH" style, so that should add some more variety too.
Remember when the first real trailer came out (not that one little teaser), it was the most popular video on YouTube for a good couple of days.
