WotC does have playtesters - you can see the little beholder icon on them on their forums.
That said, I'm kinda curious what you'd do if you were a playtester for the PH3, and let's say you had 2 whole months, while not playtesting anything else, to playtest that book. How much do you think you'd get done? And how easily would the, say, two WotC guys who read your findings find it to process your groups' findings and implement important changes.
Now change it so you're also playtesting two other books at the same time, say Martial Power 2 and Monster Manual 3.
And that job of deciphering results is a pretty harsh one - I know a _lot_ of people who say something is "broken" when it's, say, 5% out of expected bounds. So you need to hope you're getting truly constructive criticism from the playtesters.
I know this was meant more rhetorically, but I thought it was an interesting question since I have very little insight into the process of professional playtesting. How many sessions per week? Is information coded by priority? In a short 2 month timespan would the group be limited to one tier of play? How many products would a group simultaneously test? Would the DM be WotC's "caller" or would other players have a direct means of providing feedback too? Are different playtest groups synched up so that each has it's "niche" (I.e. The large party, the small party, the party of all strikers)? Is there some standardized process/form or is it a more organic process unique to each table?That said, I'm kinda curious what you'd do if you were a playtester for the PH3, and let's say you had 2 whole months, while not playtesting anything else, to playtest that book.

I would buy more books if there were more books to buy.
I cannot believe you are really serious here. You think the volume of errata is what it is now with NO playtesting.
It's three years after the PHBI was released and they are still "updating" the classes from that book. That seems to indicate that something is terribly wrong with whatever process they are using to "playtest' the material. The amount of errata for 4E is ridiculous and should be embarrassing enough to a large company like WotC to make them change their playtesting process. Pathfinder's core book is much larger than PHBI and it has a tiny fraction of the errata (mostly typos instead of rules rewrites) that PHBI has. This shows the difference between doing enough playtesting to make a balanced, complete product and trying to rush the books out the door as fast as possible and trying to fix them afterwards.

Personally, I'd be looking at having lordduskblade and a few of the other Char-Op guys/gals brought in. They caught a lot of broken stuff right away and also a lot of really garbage stuff. They have a solid grasp of system mastery and would give some additional insight. Their opinion wouldn't be the only ones of course.
