"Any circuit takes about two years to stabilise fully. In the first year, the time gap between start of the race and completion of construction was very little. This time around plenty of grassy banks have been added at different points on the circuit which should cut down on the dust. It was all mud underneath the temporary stand which has been tiled now.
"From October 1, we have banned any movement of cars on the track. We have got specialized track sweepers with builtin brushing and water-mist system too."

Other news: No penalties for drivers doing stupid things at the previous Grand Prix. Expect more gearbox and engine penalties though, through the weekend.

Weather will probably be dry, the area could use some rain leading up to the weekend to scrub the skies and make for a less drab/smoggy/dusty sky.

Thoughts:
Seeing as Red Bull dominated this circuit last year, I fail to see why Vettel won't do the same this weekend. Ferrari ought to be on damage limitation this weekend and hope for an Alonso podium, not sure if they're bringing updates to India or not. Teams might have some issues with that too due to the lengthy/awkward customs process in India.
The races tend to get processional this time of the year as the updates become less frequent and everything settles down rather quickly, the tyres become pretty much known and such. I'm guessing they will extend the DRS zone from last year to slightly improve things, but hopefully the race gives us something good.
