I'm not sure what you mean by reinstated regarding TrueAim, but there's nothing to say that TrueAim is gone. Maybe you mean TrueAim as it was in TW11? What I did learn yesterday is that there will be a lot of different camera angles and options this year, in follow-up to a question I had about TrueAim camera finishing camera cut options.
I think we saw Amateur or Pro play difficulty in Mike DeVault's demo yesterday. I can't gauge much about how I'll play the game from that.
We don't know yet what sort of aiming marker we'll have in Tournament difficulty, but I'm sure it won't be as precise as what we saw in the video. I certainly never expected to have the sensation of moving a thumbstick feel like a real golf swing, but I've always thought it could model the mechanics of it more realistically... Links 2004 proved that to me on the XBox!
I haven't seen anything yet about changes to career mode so I have no idea what might be new. I suspect there will be some changes, but I'm not banking on anything eath shattering.... it has been bland to me so far, so there is room for major improvement here.
I'll buy he C.E., but I'm hoping that none of the extra five courses are fantasy courses... they do absolutely nothing for me and will be lucky to get played once (just to remind me how bad I hate them!). I get five courses for $10 extra, and that sounds like a bargain to me... I really don't care about the rest of the stuff offered on the C.E. Green jacket ceremony? I'll probably click out of it before it finishes anyway.
Tiger's legacy mode? Of no interest to me... I buy golf games to build my own character and play the game with what I've invested in his developement.
I'm not excited about TSC because of the video, I'm pumped about it after reading Fred Parrow's blog about it. He plays the game with the same mindset as me. He sold me on TSC as being revolutionary with what he said in his blog and in his answers to my specific questions about it in the TW official forum. Will we get carnival pins again this year? Don't know for sure, but I suspect we will.
I think you may have missed his comment also that the physics of all shot types have been improved for the better, not just chip shots. Fairway woods now have the proper trajectory, which have always been almost as bad as chip shot presentation. As long as I've harped on the need for tempo in this interface, I owe them a fair trial of it to see how it feels myself before I pronounce judgement on it. I've talked to two Game Changers who've had their hands on it now, and the both say they can't fully describe what it feels like, but both say it feels a lot better and engaging than what we've had.
