I think, realistically
Hamilton is still in quite a safe place - he's gonna lead after Nürnburgring no matter what. Ferrari looks to be very strong, really, from here on (the fluctuation in performance continues - 0.5 secs in Ferrari's favor now), but the propability of anyone besides Ferrari or McLaren finishing in the top four is fairly small and will remain so 'till the end of the season. It's even more impropable that we'll see a high number of Ferrari one-twos ... not every track features the high speed corners and mild temperatures that suit them so well. It's race by race for Massa and Raikkonen, looking at the numbers doesn't really make a difference in their situation - just go for wins and see where it gets ya.
There's a clear conflict of interest inside McLaren, though. Whereas the team wants both drivers to finish as high as possible for the WCC (especially when Ferrari is showing strength), Alonso knows very well that his chances of a 3rd WDC are contingent on the Ferraris finishing between him and Hamilton. Chipping two points per race is enough, theoretically, but he's as aware of the propabilities as anyone - Hamilton will still finish higher on occasion. Of course as far as Ron is concerned, he will guard the team's interest first and foremost. And it just happens that getting both drivers to finish as high as possible, and ahead of the Ferraris if it's feasible, is the only conceivable course of action. That plainly obvious logic, no matter how "evenhanded" the treatment of the drivers is by any conceivable standard, pretty much ensures Hamilton's WDC - if McLaren can match Ferrari in general. Managing this can't be the easiest task Dennis has faced.
Renault weren't happy at all after Silverstone ... Enstone isn't too far away and they'll go over the situation there first thing on Monday morning. The HQ is keeping on the pressure, insisting that the team must always be among the top three, there's always the (almost) unmentioned prospect of the parent company "losing long term interest" in F1. Now, obviously, everything must be geared towards achieving "the minimum" of starting to beat BMW towards the end of the season. Alain Dassas did his part of setting an intermediary goal at the Turkish GP (
http://www.autosport.com/news/report.php/id/60662 ) ... new parts worth 2 - 3 tenths will be introduced at the Spa tests, and the new front wing at Hungary. Another thing how much BMW Sauber can improve meanwhile.
And btw, our Indian F1T posters might do well to keep an eye on reports that Spyker is considering whether Karthikeyan should race for them in two weeks' time already. There are other candidates, too, but given that he was at Jordan already, perhaps he has a kind of an inside track as a replacement driver - and his sponsors can't hurt either as money is as tight as ever for the team.
Edit - Besides the scrap for win (a tacticians' race), I enjoyed the battle between Couthard, Rosberg and Massa ... they went at it for many corners on end in quite a spectacular fashion.
