I'd be for Nintendo to be the publisher for Iga, but seeing how the targets were Sony, MS and Steam it makes me wonder who it could be. Capcom has a history for releasing on the three platforms and working with Inti so there's a high possibility it could be them. Bamco seems more Sony aligned with a very minimal PC presence so I feel like they aren't really in the running. Squeenix? They seem more vested in helping indies, release on all platforms (though they do have a Sony bias) and I could see getting behind this. Maybe even Sega, though I feel it might be a lower possibility since their move to concentrate more on the PC and mobile market (though I guess as publishers it wouldn't matter).
