I think when D&D 4.5 comes out next year, they will increase the number of abilities 50%.
With Strength, Constitution, Agility, Quickness, Intelligence, Learning, Charisma, Wisdom and Appearance; and how all races get one more +2 to a floating ability (so Humans get two, both floating), this should allow the game to support lots more races with individual "shticks" (i.e unique subsets of favored classes)!
Regrettably, we need to buy a new set of PHBs to get the new class write-ups (whose powers are keyed off the nine abilities) but I still think this is better for the game, and so well worth waiting for!
