I don't think that DotA will have any influence on any descision of Square Enix. I would say have a little protest sort of thing outside of Square Enix America, but not demanding, simply showing how much we love the series... But that would be difficult for Chrono fans outside of the US...
Which is why we'd get fans in Europe to have a gathering of sorts outside of the Square Enix headquarters in Europe, and get the Japanese cult fans in Japan gathering outside of the main Square Enix headquarters. Of course, if anything would have any effect whatsoever, it's the last one, as Square Enix--at least the Squaresoft part--has always paid far more attention to Japan than anywhere else, as it should, since it's a Japanese company.
The issue with Europe has always been translation difficulties however. Many claim that Square Enix intentionally left Chrono Trigger out of the Final Fantasy PSX rereleases in Europe because they didn't want to create more European fans, and that's just idiotic ridiculous nonsense. Consider how many languages you have in the PAL region, vs. just one for the NTSC region. Now consider just how difficult it is to translate from Japanese to English. Also note that for a Chrono Trigger European release, they would have had to create a new translation for each individual language. Considering it was just a SNES emulated port of the game to begin with even for the NTSC region, it's not surprising it was left out, as doing a new translation for Europeans might have prompted doing a new translation for English as well, which would have caused problems as the United States and Canada also speak English, albiet two different dialects, and we would have been left out translation wise. Then they would have had complaints about no new translation for the Final Fantasy games and you can see where this would start being a serious problem, when the whole point to Final Fantasy Chronicles and Final Fantasy Anthologies was to garner more interest in Squaresoft products amongst Playstation fans who might not have been around or might have ignored Squaresoft during the SNES era for one reason or another.
This is why I have high hopes for a Gameboy Advance port. Given that Final Fantasies IV, V, and VI have all gained new translations in their ports to the GBA, and given that right now Square Enix has rated the chances of a Chrono Trigger port to GBA as 50/50, we may see this issue finally resolved. Now while I doubt they'll take the time to retranslate Chrono Cross and rerelease it to the PAL region, I certainly don't see why they wouldn't retranslate Chrono Trigger for the PAL region while doing the same for the NTSC region in a new GBA port. If anything, doing so would set the stage for a new Chrono game as it would introduce the series--officially--to the European market. And considering how many Japanese-only games have started to be released to Europe--among them, Kingdom Hearts: Final Mix(leading some Kingdom Hearts fans, including myself to hope that the Final Mix version of KH II will be released in the U.S.)--I daresay that the Europeans have a high chance of seeing Chrono Trigger released there in a GBA port.
So, that begs the question of whether we really need to do anything at all, doesn't it? If what I'm saying here has any basis in reality, then we might be fine. We might see a new Chrono game without any work at all. But I wouldn't go so far as to say that. In fact, that would probably be a bad assumption. So, what do we do?
...Damned if I know...
