Is this coming to ps3 too? I'm curious

PS3/psv/ps4 in Japan.  Definitely ps4 in the rest of the world but not ps3. Vita will get an Asian version but I doubt the west will.  

Hopefully dragon quest heroes 3 is Ps4/vita only.  

I've still not played the first one. How does it play composted to dynasty warriors? Does it have boss fights?

Still not a PS4 exclusive? They need to discontinue PS3 support in Japan, like they did INSTANTLY with the Wii, to raise WiiU sales.

Why can't it just be a DQ Action RPG without the hoarders of monsters. Basically, a Zelda+DQ game. I'd like that much more than the warriors aspect. All that aside, it's looking good but the main hero's color scheme is a bit odd.

Because they feel it's throwing money away not making it for ps3. I presume this will be the last one that's on ps3 so 2017 onwards ps3 versions should pretty much die. 

I really hate the bland levels of dynasty warrior games. It's like a button mash fest which is fun to start off with but for me, gets boring very quick. Do these games play in a similar fashion?

It can get boring. There are bosses kind of like Monster Hunter. Story mode didn't have too much button mashing for me. Story objectives are not like DW at all. Leveling is a thing+ RPG equipment. Basically in between KH and DW level of button mashing. You can still use classic DQ spells and abilities with mana rather then just mowing down enemies all the time with regular attacks.

First one had Crafting, shops, character interactions, quests unlike DW games.

I was hoping for the same, guess it still makes sense to make a ps3 version
