Putting a mainline FF on the wii isn't the answer because that's not the series' audience..
That's where you're wrong, brah. Where was the FF audience on the PSX before VII was whisked away and sold a record number on the platform? You make it sound like the FF fans are hopelessly and forever intertwined with Sony machines exclusively, but we all know that isn't true.
I think Nomura's zipper magic has worn out and the series needs to take a whole new direction (ala Zelda Wii), and possibly start fresh on a new console altogether. After all, if they do decide to sprinkle some western influence on the series, why not do it on the most popular home console in the west?
Well, FF has become less relevant in the industry in general. Despite dwindling sales, they still (for the most part) sold better than they did pre-VII because pre-VII was ONLY Japan. Hell, FF8 sold more than 7. So where is your argument?
I'm not saying FF fans are mostly concentrated on Sony consoles, but there's definitely an overwhelming amount. And many of those went to Microsoft when 360 came out and Sony took forever to release ps3.
What I'M saying is that I don't FF is no longer relevent enough for it to recieve a revival strictly
because of wii. FF is not DQ. Most of DQ's sales come IN Japan, whereas FF is a far more internationally sold franchise. FF has built up a brand in the US, Canada, Europe and the rest of the world; DQ hasn't. It has also built up its brand on high end consoles with crazy product values. I think that going to the wii would do WONDERS for the wii audience in Japan, but would be a disaster outside of Japan. After all, we know how well rpgs have done on Nintendo consoles in the past 3 gens. :lenowned
With the exception of games like Tales of Symphonia which are only successes BECAUSE of a heavy rpg drought on Nintendo consoles and heavy word of mouth, people don't think of rpgs when it comes to the wii. DQ10 could change that, like it helped changed the portable rpg landscape, I *still* doubt that putting FF on wii is a good idea.
That's doing away with over ten years of brand name build up: from 7 up till now. That's like putting RE games exclusive on a Nintendo console, and we know how THAT turned out.

I'll agree that the series needs new life. Something that'll give it a new boost in terms of interest and sales ala RE4, but I don't think that putting it on the wii is the answer. Nintendo fans have clamored for high profile series on wii and most of those haven't done so well in the past, have they?
No, what FF needs is this:
1. New life, a reinvention so crazy that it will make people who stopped after 8 and 9 and 10 to become actually interested again.
2. Grow up so it interests more than people outside of the animu and/or tween circle. Many of the people who helped build Square's empire are now tired of their shit, grew up, and moved on and while they're still popular with teenagers, I really wonder HOW popular.
3. Shorter development cycles. This is the big one. A part of the reason FF7-10 sold so well is because they came out YEAR AFTER YEAR AFTER YEAR. FF7 in 97, FF8 in 99, FF9 in 00, FF10 in 01. These days we're lucky to get a new single player main series FF every 4-5. That's too goddamn long.
