the problem with that eugene is that, while yes in a perfect world (say a brand new game for example) then your arguement would be valid, but unfortunately there a people in this game with capped gil already that will force inflation across everything. unless of course these people with capped gil don't login or play the game before november and make 10mules and share 10m between each mule.
basically my point is this, it's not going to be an exact 1/10th rate, its going to be somewhere in the middle due to inflation. it will drop dramatically from what we are seeing, but do not be suprised if all the good high tier equip is millions and millions still.
The issue is, even if people try selling it for near the same prices as things are now, very few people are going to be able to buy that stuff, thus the price will eventually go down to near equivalent "2.0 prices" when people find that they aren't going to get the amount they're asking for.
