These will most likely be expensive weapons, due to the fact that the E-Liter's original costs 12500 gold and the Nozzlenose seems like a Blaster, meaning it will come after the normal Blaster (based on the level it unlocks at).
That being said, my thoughts on both:
Finally we have another Beakon weapon, and fittingly on a weapon that's ment to camp, making it a great support role. The Kraken makes its weaponset equel to the Krak-on Roller, but invincibility and close combat can be usefull. I see this weapon being used alot.
The Nozzenose is hard to evaluate whitout stats, but looks like an alternate to what the Rapid Blaster tried to do: More coverage, less kill. Although this weapon has one up on other blasters, as it's three-burst is (methinks) ment as a way to correct your aim during it's burst.
I was expecting a new map, but atleast we have a Splatoon update this small out of the way already, so that we have more space during the E3 presentation.
