Can a bladebound Magus' Blackblade learn a spell (from item power?)

[Erroangelos]

The question in the home session upon reaching level 3 is whether or not the Magus' black blade learns a spell through the intelligent item power chart or not. The current idea is that learning an item power is an ego modifier and the black blade chart specifies certain ego modifiers in growth which means the item cannot learn a spell. Players argue that "Each intelligent item should possess at least one power, although more powerful items might possess a host of powers."[b]

Any official decisions on this subject?

The Black Blade's powers are what's listed in the Bladebound archetype. No more and no less.
