Actually, I tend to believe him. In google.com.au, the first letter typed brings up different results and not all are commercial brands, e.g.
A = AFL (one of our sports sites), next ANZ (a bank), ATO (our IRS), then Amazon.
B = BOM (Meteorology bureau), Bunnings (like Home Depot), Bigpond (ISP), Big W (Woolworths)
I can't raise Google Instant in google.co.nz but when I try the UK site, I get the UK predictions, e.g. Argos before Amazon.
