Its interesting that the Dev chat specifically said
"Regarding 25 daily quests to turn in when the expansion goes live, this is something players have been able to do for the last 2 expansions and we aren't talking about changing it now."
Now, something you should know is that 4.0.3 nerfed the gold on dailies to a little over 7 gold, thats almost half of what it was prior to 4.0.3. Basically they halved the experience gain from dailies. However, anyone who had already done them or just had them in their quest log in preparation for Cataclysm gets the full 13 gold, or the full amount of experience essentially. I'd almost say that Blizzard is sending mixed messages, but then it really just comes down to them saying they are not stopping it, doesn't mean they can't nerf it to lower its value for Cataclysm.
