Used google translate to get the basic gist of the article, but very interesting.
They said in 2015 with the announcement that they were making a remake that they weren't just bringing White Day back to be just a remake of the original, the remake is just their first project. They talked about how they want White Day to be Korea's premiere horror game franchise, it was their plan back in the day as well but it wasn't successful at the time. However they all believed in the vision and over the last decade various members had been saving up and planning so they could reform and keep afloat for a while as they made a whole remake and enough to go beyond that too. Plus the recent mobile version was a big success.
They talked back then that their plan was to make White Day games until at least 2035, releasing at least one new White Day game every 2-3 years. They had plans going from 2015-2035 for White Day, and mentioned their goal was to turn White Day into an iconic Korean horror game series. They have formed planned for the next several entries they hope to surprise people with, starting with the remake of the original but to then after the remake to start making new entries for White Day. I will say I didn't expect Swan Song to turn into White Day 2, though.

They confirm the PS4/PC remake took longer than expected because it was their first time developing for consoles, they had experience with PC and Mobile but not with the Playstation 4, they had some trial and error but got it to the quality they wanted and why it released so long after the mobile port than intended. But their experience will help them greatly for their future titles.
He mentions that they put a lot of care into the PC/PS4 version, redid stuff, put in new effects, lighting, etc., not available in the mobile version, put new physics on things. He does say that because of the mobile version the quality of the game's graphics may not be to the level current console players are used to, but he hopes the extra work put in shows and people will be able to still love the game even if it's not the most graphically impressive.
Confirms the new character in the PC/PS4 version of White Day has completely new stuff built around her in the game hidden away. You can play the whole game and never meet her in the new remake, but there's secret events and chains tied to her. She doesn't interact with the main story because she was never planned for it, she has her own story you can take part in though which leads across its own new story path in the remake.
He says they made Very Easy Mode for casual players, so more casual audience can have fun too and be able to enjoy it. But he says if you're a horror fan and want to be challenged, you should play the game on hard difficulty.
They mention they have some plans for the Japanese-exclusive (currently) BlazBlue costumes that are a pre-order bonus in Japan, they have some things planned but it's to be announced later. Mention the collaboration with Arc System Works was for more than just these costumes.
It sounds like there may be an optional VR mode, but they think players expectations of the sequel will be high after the remake for audiences and wanted to make a more proper follow-up.
Mention White Day 2 is being made on Unreal Engine, and should see release in 2018. It's actually further along in development than we probably think it is, they recently sent it to rating boards since content wise it's about done, just in tuning right now.
They want to thank fans for their support, it was because of people still loving White Day 16 years later that they were able to return to it. They hope the remake makes people happy, and they also say if people wanted more than just a remake of the original game to keep their eyes on their current actions. They plan to turn White Day into Korea's premiere horror game franchise, and there is a sequel that actually is not that far off from releasing, and other projects they have in the works they hope to surprise people with.
Also a few new screens of the PC/PS4 remake:
I'll make a new topic on White Day 2 and the details.
