It might have already been said, but everyone is assuming that he will carry on this amazing run of form he's in, for another 4 years or so, which is pretty ridiculous to be honest. It has to end somewhere (I'd like to think so anyway), and that might be later rather than sooner.
No, if people were saying he'd finish his career averaging 65, they'd be assuming his run of form would continue forever. Even if Ponting averaged 40 with one or two centuries every year for the rest of his career and played for say 5 years, he'd still finish his career with the record for centuries and probably for runs as well.
To put his current age in context, look at Steve Waugh. He's a guy who began his career pretty young like Ponting, and developed from being a solid batsman to a great one as his career went on. Ponting turns 32 during this Ashes series, and has currently played 106 tests. Waugh, at his 32nd birthday in June 1997, had played 91, and he retired in January 2004. Waugh finished up playing 168. At 32, he'd scored 5615 runs @ 49.69, and finished up with 10927 @ 51.06. Waugh declined pretty badly in his mid 30s and his average dropped from 52 or so down to 49, before he got it back up again with a run of good form before he retired. Between turning 32 and retiring, Waugh scored 18 of his 32 centuries. Ponting already has 9,000 runs and 32 centuries.
Now, Ponting may very well fall a long way short of that, but the point is merely that there's no reason to assume that he doesn't have plenty of cricket left in him. Some guys like Tendulkar struggle from their early 30s on, while others like Lara and Waugh find the best periods of their career come in their early to mid 30s. It could really go either way, but whether Ponting declines sharply within the next couple of years or repeats his last 4 seasons over the next 4 years, he's still a good chance to break a number of records.
