Certainly looks like it has the potential to be something I could really love.... but then again so did Mugen Souls.
For what it's worth, Mugen Souls Z, so far, seems to fix/smooth over the mistakes Mugen Souls made. I'm enjoying that one a lot more.
As for Eiyuu Senki, I'm not familiar with Fruit Bat's localization work. All I know is what I read from Andrew's 99 Spirits review and he said they localized it very well. So that's promising at least, that the game in the hands of a competent localizer and not something like O~3 Entertainment's botched translation of Chaos Wars for PS2.
I actually just got through reading your preview report on Z, Din. Good stuff.
I am real happy to hear Compile Hearts tightened things up. I still firmly believe they will have an utter stroke of JRPG-Awesome-ness someday and perhaps that day is drawing near.
However, even if it were the Compile Hearts title I have been waiting all of the PS3/360 era for I don't know if I can't play it right now. I just simply am burnt out on the formula ATM. Sometime after Disgaea D2 I just lost the taste for that NIS flavor, be it a Nippon Ichi gig or CH/Idea Factory. Something akin to over-eating your favorite food even after you've had your fill of it you might say.
I need me some darker toned, more thought provoking material before I return to the light hearted anime fair. I still have Neptunia Victory and Guided Fate paradox in my back pocket as well.... thing is, between NIS and Namco Bandai for the past year or two I reallly need some SMT, Drakengard, SHadow Hearts, Lost Odyssey and maybe even Dark Souls in my life right now.
EDIT: I'm even having a real hard time getting through the last stretch of Atelier E&L which I was really looking forward too. This happened to me before and it was Persona 2 (per your suggestion if I recall Din) that proved the perfect fit for me.
