I like the wheat beers sooner, too. Not that they're disappointing after several more weeks, but some yeasts flavors will settle into the beer a little more so that it's sort of plain.
I did a Hefe-style all-grain with S-33 yeast (not the first choice, necessarily) and it was really perfect at 2-3 weeks. A month or more later, it still tastes like a wheat beer, but less like a good Hefe...milder banana and spice notes. I did a batch of the same beer with WB-06 (more common choice for a Hefe) and tried it at 2 weeks. Stronger banana and spice notes that I expect will be around a little longer.
