Ok trying for 4th time to send this now since wow.com comments seem to bug a lot!

You can just do dailies in wotlk and get 600g PER DAY with EACH 80 YOU HAVE. If you start doing dailies now and lets say cata comes in 90 days: you would have 54 000g in start of expansion with 1 alt doing dailies 20+ dailies everyday and if you have 4 80s like me you would have 216 000g total. Gold really is not the issue, now is it?

People HAVE to realize that while the this skill is available at 60 theres NO reason for leveling alt/main to get it at level 60. This is important part of the announcement!
First of all, from my understanding, this ONLY applies to old world and cata zones and you would STILL need to get base flying skill.
When you are 60 you wont be leveling in old world for pretty long atleast, even if its totally revamped. Unless you are making loremaster alt and that really is exception: In this point you most likely have mains with atleast 5k gold combined, because you are bored or have too much spare time, 250g is no problem.

This is only meant mainly for 80+ characters who want to fly in old world and Cata zones. Just because its buyable at 60 it wont mean you should get it, you will be in outland by the time you hit 58-60.

With this announcement as fact it pretty much says that you would still need to buy flying skill if you wish to fly in Outland or even fly AT ALL. But you can just get "Loaned mount" for free if you are just breezing thro northend in cataclysm times and even in outland.


So to recap:

You need to get flying skill+this one to fly in old world and cata zones. There is no need to buy flying when you are doing outland and northend as they are easily done by land mount like they were designed and done before the whole mount revamp. The saved time is only marginal when you do LFG and are decked in helmet, cloak, chest, shoulder, weapon, trinket heirlooms.
I had chest and shoulders and was 65 before I even left hellfire as I was also doing dungeons thro LFD with my recent alt and I had ZERO need for flying mount during that time, I never needed to cross hill to save whopping 2 seconds or 20 seconds to "not kill 5 mobs near the quest item".

When you are done doing quests in outland and northend you easily have more than enough gold just from questing itself. Northend questing gave easily one thousand gold at first time without LFD, as that didnt exist that time. Since you are did not spend that on northend flying or outland flying, you can get this 250g flying without hurting gold flow you are never going to use for anything else, anyway.
By the time you are 85 you prolly have gotten 2k gold from questing itself, just like in northend.
