Just a reminder, here's the list of DQ games we haven't gotten in recent years:
Dragon Quest Monsters Battle Road Victory (Wii Arcade/Card Game port)
Slime Mori Mori 3 (Rocket Slime 3) (3DS Pirate Slime Action Game)
Dragon Quest Monsters: Terry's Wonderland (Monster Catching Roguelike)
Dragon Quest 7 3DS (JRPG)
Dragon Quest X (PC/Wii/WiiU JRPG/MMORPG hybird)
Dragon Quest 1 Mobile
Dragon Quest 8 Mobile
Dragon Quest Monsters Super Light (Monster Catching Roguelike / Puzzle and Dragon clone hybrid)
Dragon Quest Monsters 2: Iru and Luca's Marvelous Mysterious Key (Tara and Cobi's Mysterious Key) (Monster Catching Roguelike)
We won't be seeing Battle Road Victory, it's way too old. Pity, as it was a nice card game - kinda expected a mobile port someday, as the interface seemed to fit and the PAD style mechanics would be a natural business plan for a game like that.
Same with Slime Mori Mori 3, unless someone like Vic Ireland or Xseed convince Square Enix US to let someone else have a crack at it, we're not getting it by this point. (Since SE US would then have to explain to SE JP why someone else could make a DQ game work in the US while they said we Americans just don't buy them, this is doubtful.)
DQ1 and DQ2 mobile were recently seen on the US ESRB site, but it was by a different company than Square Enix. Lots of speculation there - there was a company that was publishing Emulated roms on iOS, including DQ1+2 GBC, this might have been fallout from that, since the company that registered it specialized in helping other companies get their apps on all the app stores at once.
DQ1 and DQ8 both have English localization content hidden inside them. DQ1 even mentions the translators' names in the credits. (Some people from Honeywood, some people from Alex O. Smith (who does a lot of SE's translations)'s company, etc.)
I like to think the success of FF14 ARR improved the chances of DQX in the US, since they cater to a much different market (DQX is much more casual than FF14's hardcore raiding endgame) but you could take that as the exact opposite, that they're not going to risk FF14's popularity for anything.
DQM1 I've always been really pessimistic about, but with DQM2 launched in Japan I'm really doubtful we'll be seeing DQM1 ever now. It would seem to me that SE/Big N would simply skip to DQM2, which is a shame - DQM1 is probably one of my favorite games of all time.
DQM Super Light will probably be localized if only because there's a frighteningly small amount of text in it and SE has been on a major mobile push. The fact that a good chunk of the text is already in English, including several of the credits pages, hint that we might get it. PAD being so popular in the US definitely helps.
2014 is the 25th Anniversary of Dragon Warrior in the US. It's also the 15th Anniversary of Dragon Quest Monsters.
If we don't see at least a token release of DQ stuff in the US this year, wrap it up, SE has written us off as fans.
