He's focused on DS right now

Of course he is, I didn't say he should switch focus. It's a question, not building an raising capital and building an orphanage for disadvantaged youth. Let's try to keep it in perspective lol

He's not a machine to ask games out of.

No, he is a human being. He made PT. He makes games. That's his career, he's the exact person to ask.

He ALREADY knows the interest in a horror game from him, but it's selfish to harass him

Whoa there big fella, nobody said to harass the guy. When someone, I don't know, wants a Taco Bell item to come back, they tweet the company. It isn't harassment, I'm not encouraging anyone to be rude to the guy.
