I dont see how adding another tank class would suddenly fix the problem of so few tanks, those that want to already are and those that dont wont touch the class outside of seeing what its like.

Granted new tanks will come and thats good, but tanks are always in short supply. The majority simply either dont want the responsibility or prefer to see bigger numbers floating around.

If and when they do add a new tank I would love for them to go the unconventional route and make a ranged or magic based tank (Engineer/Rune Fencer?).
