It surprises me how many people I see posting things about spirits getting aspir or enaspir. Why would a spirit need more MP?
They said they were making it possible to get MP from your spirits, which implies either that the SMN aspirs off them or there will be an ability similar to DRG's Spirit Link, only using MP instead of HP and with the amount healed going to the player, not the pet.
Job and Battle System Adjustments
From PlayOnline.com:
A number of job and battle system adjustments have been scheduled for the next version update.
New Magic and Job Abilities 
A host of new magic and job abilities will be added to a number of jobs for the next version update. For example, teleport spells for the white mage, a warp spell for the black mage, sneak ninjutsu for the ninja, elemental spirit MP absorption ability for the summoner, and new automaton weapon skills for the puppetmaster.
Additions and adjustments are also in store for the two new jobs introduced in the Wings of the Goddess expansion.
For the dancer, adjustments will include shortened ability delay to six seconds for all waltzes used when trance is in effect. Adjustments for the scholar will see an increase in the maximum number of charges available for stratagems, and a reduction in charge time.
Apart from job abilities, new status-specific status icons will be also introduced to further enhance playability.
Shortened Immobility Duration 
The issue whereby certain restoration magic causes the character to become temporarily immobile, will be addressed. Up until now, casting cure on a character immediately after they initiate the attack command will result in that character becoming unable to move until spellcasting is complete, even after they have assumed battle stance. This immobility duration will be reduced drastically with the next version update.
