Do YOU think we'll get a new Tank and/or Healer in 4.0? And vice versa.

i just want a new caster dps, i love playing casters and i got bored of smn and blm, well they are not what i imagine ff blm and smn should be, so i just want a new caster, don't care about anything else. and i don't like brd and mch at all, oh and to add as well that there are 8 dow jobs and 5 dom, so i think they will add 1 dom for sure, not sure healer or caster but because they already added a healer this xpac i hope it will be a caster dd for the next one
