A fine long post Exonian, and I'm not too far behind - I was 40 yesterday! lol
I completely agree with forums and the written word - it can be taken very literally, and be the cause of many unfounded arguments! But, I think in this case we both know which page we are on. Having said that, the "remote dating" thing your mate is doing sounds interesting!

I've had my Mk5 GTI pretty much since new - was an 05 plate that I bought 6 months old. I've loved every minute of owning it, but like anything you do fancy something else. Plus it's falling way behind in terms of technology. I never really liked the styling of the Mk6, but I love everything about the Mk7, so the time felt right to go-for-broke on a new order. Like you I intend on keeping mine for, well, as long as I can really. I wouldn't be unhappy knowing I was going to be stuck with it for another 7 or 8 years that's for sure.
Oh I don't doubt or underestimate the performance of modern diesels. I know plenty of people with them, and have driven a fair few, but like I said, there is more to my purchase than mid-range grunt and economy. Call me shallow, but the GTI looks have as much to do with it! Now, if it turns out that the 2014 spec for the GTI does includes ACC as standard, I may consider just coughing up the extra dough and adding on the Performance Pack. However, like most people I have my financial limits, and within what I can reasonably afford I am getting the car that I want as the current spec stands.
