Senran Kagura Estival Versus's Ikki Tousen DLC (and PC port) launches March 17th.
Annnd that's kind of the whole story. The long-awaited Ikki Tousen DLC will launch day and date with the Steam release, annnd "Each character will be priced at $3.99, €3.99, and £2.99, while a bundle containing all three will be offered for $8.99, €8.99, and £6.99."
I'm going to have to buy it, of course. If nothing less, to let the devs know that I love the SK brawlers and have zero interest in that watergun game they're comin' out with next.
