MS seem most likely. Sony don't seem keen to fund and with FFXIII exclusive in Japan plus Yakuza arguably don't need it. I guess I could see Sony funding it initially but only with a deal that gives them first dibs on any sales margin. Bayonetta sales in Japan show that even having a better version doesn't enable 360 sales of a Japanese title to sell better, so Sony would seem to be in a good position vs Sega
Nintendo won't fund it for sure, and they also don't need it. This seems unlikely.
MS arguably need the title in Japan, are willing to fund, have a Japan team doing just that, and have had the series on Xbox before. On the other hand, the final result is sure to be a small bump in sales and perhaps and overall failure if the title doesn't sell much in the US. Still, they might do it just on the principle every small bump in Japan is worth it.
Personally though, if I was either of the console makers, I'd ask Sega just why they don't fund it if they're so sure it's going to be a success.
Try to be reasonable... its easier than you think...
