Lightning Returns will be released in 2014 in theh west, so that fills up one part of the (calendar) year with a somewhat significant release. FFXV & KH2.5HD will very likely make it for at least the fiscal year starting in April 2014, hopefully even the calendar year.
So... Say they have LR's western release for February 2014, Kingdom Hearts 2.5HD for late Spring or early Fall (doubt they'd release it in the Summer, that's bad enough time for new game releases and probably doubly so for a re-release) and FFXV for something like November/December 2014. That'd leave early Spring, late Spring and/or Summer completely devoid of releases. They'll likely have at least something in the veins of Drakengard 3 to fill some empty space in the release schedule. And while at the moment it seems they've abandoned handhelds, maybe with the arrival of Animal Crossing & Pokemon's upcoming release selling some 3DSs, they'll try again. Something semi-big like Bravely Default 2 could very well be announced at TGS this year for a 2014 release. I'd wait until TGS is over before panicking over SQEX's 2014. They've announced stuff like Dissidia there, like, 4-5 months before release, it could happen again considering how quiet most of SQEX has been apart from FFXIV, LR & now Nomura's main gang. And if all that fails, there's still Jump Festa 2014 in December, where they could announce something.
