there are big things planned for ishgard in 2.0. it was hinted that ishgard is finished right now, but won't be put in place till 2.0. because at the moment 50 characters is all that can be shown on the screen at once, and the plans for the content in ishgard will need lot more than 50 ppl. this suggests something very big indeed. as for coloured chocobos, i believe this will come with chocobo breading
