Pre Scriptum (does that exist?): Sorry for my English, hard to express those kind of stuff not in your native language, hope I didn't write below nonsense or contrary of what I'm thinking. And yeah, that's just my opinion off course
First, JonZ is a Master God trailer maker, period. This guy rules and will be able to make an amazing trailer just showing a phone book, and phone companies will run out of stock.
Second, I hope they will be able to reach what they want to reach. They know they have a past which don't serve them to make believe to the mass they can do a real simulator ala rF2. They are fighting to prove they can go further than what was due to publishers they worked for. They get rid of any publisher to be able to do what they wanted to do. I have big hope as in one year I saw so many improvement on physic department. They had to first go to graphics to bring people into the project, and they sure know how to appeal on graphic side. Now from past months they focus a lot on physics and FFB and make amazing progress, even if lot of work still need to be done. Possibly Project Cars 1 will not go enough further for our current taste, possibly only a Chapter Two or Chapter Three will reach that, anyway I have lot of respect due to the wishes of this team and the work they do to reach them.
Third, it's a really smart and nice team, real professionals and really good technicians with open minds. I enjoy to share, discuss, participate when I can with those Guys. Releasing a nearly daily build for mass people is an huge and difficult work, and that imply a perfect method and organisation which impress me (as a dev, and a game dev in my previous life).
And I don't think the fact they also plan consoles mean the PC version will be lowered. Consoles version will be lowered if needed due to possible technical caveats, but the computer version will be as far as they can go. Yeah, I'm respectful of those guys. ISI don't have to prove anything IMHO coming from rFactor and so much really good Sims. rF2 is IMO the most amazing Sim currently running on my computer. SMS will have lot of work to reach such level, and AFAIK they don't want to just reach a level to appeal mass market. They want to reach a certain reputation, a certain level in Sim department. Hat Off for the strength they put on that.
