Um, no.
Right now, as has been stated before, Square-Enix are concentrating their strategy on certain IPs, such as their huge moneymakers--Final Fantasy, Kingdom Hearts, Dragon Quest--as well as a few others including potentially a couple new IPs.
The fact that Chrono Trigger saw a sudden release on the DS, with all new content that tied it into Chrono Cross to boot, suggests quite highly that there is some interest at Square in releasing something new in the Chronoverse. It's possible that they may pick it up again in the near future.
On the other hand it's also possible that Chrono Trigger DS just didn't sell enough copies to make it worth it to them. It sold...790,000 I believe, which sounds like a lot but really isn't, compared to best sellers like New Super Mario Bros.
And yet...they still keep C&Ding Chrono fan projects...the fact that they keep doing that suggests there's enough interest on their part in wanting to make something new, but not enough to actually get around to doing it.
Really at this point we can't do much of anything anyway. We're not Japanese, and Square doesn't care anywhere near as much about North American or European customers as they do their core Japanese customers, as they keep proving with their release of extra story content for Kingdom Hearts(that they then go on to reference in their releases in NA and Europe as if we should know it already or just find out from elsewhere, which we wouldn't have to do if you'd just release the extra stuff in NA and Europe where it WOULD be profitable...)
So what we do is irrelevant. It's how the market in Japan pans out that'll matter.
