I don't know. If you twink out with enough metamgic feats to increase damage + feats to reduce metamagic cost (or metamagic rods, whatever), a wizard could probably equal or exceed a psion in nova ability, except it'd be less costly in daily resources to the wizard, most likely. The psion will have better saves (increasing with the augmentation), so eh...
The main advantage for the arcanist being that he CAN apply tons of stuff to the same spell at once. A psion needs to lose his psionic focus, and while he can use some tricks to get it back the same turn, I don't think any of them let him apply 2 metapsionic feats twice. Maybe the feat to make his psicrystal hold a psionic focus allows that... The other trick I know of (which would not help for nova) is the swift action power that grants you a move action (which you can use w/ psionic meditation to regain your focus, arguably not worth the pp spent, precious powers known slot, and loss of a swift action).
