Canned Dogs translated a recent blog post by Hideo Kojima in which he talks about his meeting with Kinoko Nasu and Takashi Takeuchi, the cofounders of Type-Moon -

The meeting only lasted for a short while, but the meeting was pure enjoyment and I have not had something like that in a while.

It was the first time we met but I felt like we had already known each other for a long time, I felt a kind of affinity that was like deja vu.

It’s a special privilege that only creators have. Even when age or race are completely different, we can still understand each other instantly when we have the same "smell."

Even though we’re from completely different areas, it does raise my spirits to get to know people who are working really hard and suffering in agony but continue to still create new work.

It makes me feel that I have to continue working just as hard as they are too!

Unfortunately, there is no word on whether or not they will be working together in the future or anything like that. Type-Moon's recently aired Canaan was based off of a scenario from 428: Fuusa Sareta Shibuya de (aka the Wii game that got a 40 from Famitsu last year), so the company doing a project based on one of Kojima's previous works is not outside the realm of possibility. But don't hold your breath...
