A few thoughts:
Assuming we get the traditional belters at Adelaide Oval, The 'Gabba and The M and SCG, we are most likely in for a high-scoring series.
The one big thing John Wright has done is gone some way to curing the mental problems India have had away from home.
The spectatre of winning a single Test outside the subcontinent in 14 years (in Zimbabwe) cannot have been much of a confidence-producer, but the notion that Indian batsmen have trouble with a bit of extra bounce than they're used to is quite stupid - no, I haven't watched every single series in that time, but I highly doubt batsmen will have constantly fallen to gloves to short-leg, splices and top-edges.
It is far more likely that, in thinking "we're playing overseas and we might have trouble with the bounce" they have failed to maintain their normal concentration and have played poor shots, ie inside the line when defending, angled bats, drives on the up to the wrong balls, hitting the ball in the air when it's not difficult to keep it on the ground, etc.
If Dravid, SRT (as he seems to be popularly known on here), Laxman and Ganguly can forget this and actually think "hey, these pitches aren't much different to ours at home - sure, they bounce a bit more, but I'm good enough not to worry about that".
If, on the other hand, they decide (sensibly) to leave a bit of grass on the wickets, watch out - McGrath and Gillespie will destroy anyone, no matter how good, on a seaming pitch. This could be the tour that finally exposes Virender Sehwag's limitations as a Test-match opener. As for Aakash Chopra, I don't know - he averages 50 in FC-cricket, but so do plenty of Indian batsmen. Sridharam Sriram averages 60 in FC cricket and he's only played ODIs.
Shiv Sunder Das and Sadagoppan Ramesh did OK for a while, but neither have exactly got brilliant FC averages when you look at those with 50 and more.
If the middle-order gets some flat pitches, we're in for a lot of big totals. Brett Lee and Stuart MacGill (and anyone else who plays) watch-out.
Similarly, if there's no turn in the wickets (which there is no reason to expect there to be, except at The SCG) expect to see Kumble and Harbhajan exposed. Khan and Nehra seem to be the only seamers in India ATM who rise above mediocrity and even they haven't exactly got flash domestic records. With Prasad and Srinath seemingly gone and Agarkar seemingly not the bowler he was last time (where he actually averaged under 30 at a very good economy-rate for the first 2 Tests) expect to see lots of runs from Ponting and the gang.
The likeliest score I reckon is 3-0 or 4-0. Thank God West Indies made an impossible run-chase and Vaughan managed 183, otherwise Australia might be on another 20-Test winning streak entering India.
