I picked this up Tuesday night; technically like 12:01 Wednesday morning. The crappy thing is I actually was at the register with a copy in hand about fifteen hours earlier at like 9:00 AM Tuesday because Walmart mistakenly had it out a day early, but their system wouldn't let them ring it up. The Customer Service Manager (CSM) said something like, "It must be recalled" but I quickly explained that it was probably because it wasn't supposed to be out yet.
Anyway, I've played it a little bit since picking it up, although I've had a lot of crap going on that's kept me busy. I think I'm going to wait to really dive into it until I've picked up a wheel for my PS3 (got one for my 360 for F1 2010 a couple months ago). I find it pretty sloppy with the controller, which I found odd because I managed Forza Motorsport 3 just fine with the controller.
The GT fanboys aren't happy with the reviews the game have been getting, and I'm surprised that it's scoring as low as it is, although it's still scoring very well, but so far from my initial impressions with the game... I have to support the reviewers rating it a bit lower than FM3. The game does an awful lot, but some of it is of limited or no use to the vast majority of players and it seems to be missing some stuff that I was able to do in FM3. Importantly, one of the advantages this was supposed to have is that it was supposed to look a lot better, but my impressions so far is that it looks about equal at best and in some ways looks worse. The menus suck, the default controls are retarded (Why would I use face buttons for throttle and brake? I changed them immediately.), the soundtrack is weak (although I never cared much for FM3's soundtrack, either), and the impressive car list is a little deceptive.
Yes, the game has well over double the cars of FM3, but only 200 of them are of FM3 quality which is less than half of the 400+ of FM3 and the other 800+ are outdated and don't even have a cockpit, which just isn't good enough. The game has fewer tracks than FM3, as well. I've heard so much about how much more amazing those 200 premium interiors look, but so far I'm not seeing a meaningful difference between GT5's interiors and FM3's interiors, and FM3 has more that twice as many. GT5 boasts twice as many cars on track, but it consequently suffers from some framerate drops, screen tearing, and some iffy environments that often fall short of FM3, at least in some details. It has day/night and weather, which is an advantage over FM3, but it doesn't do it as well as some other console racing games. As a recent example, rain looks a whole lot cooler in F1 2010 than it does in GT5.
And what's with the intro video? Yeah, it's not important, but it seems a bit of an odd choice to start off a racing game. The video spends a good deal of time showing clips of digging up iron ore, turning it into metal, and manufacturing cars, which probably one player in a hundred will be interested in watching and the other ninety-nine will skip it to save themselves being bored to death. Then they slapped on a Mister Rogers musical score to accompany that whole
PBS sequence.
Don't get me wrong. It's still a very good game and I like it, but it's not perfect and not as good as it could have been, and so far I'm not so impressed with it.
So I have ordered mine although I won't see it until next week 
I did pre-order originally but when it got delayed I cancelled my pre-order, now I feel silly!
