Like I said, Steins;Gate.
I'm counting on it being one of the best shows this spring. Nitro+ come up with some mint stories so as long as it doesn't go down the same route as Chaos;Head (Anime sucked but the visual novel is brilliant) it'll be epic.
Edit: BTW, If anyone likes that splendid song that plays in the PV, It's called Another Heaven by Itou Kanako from the album: Chaos Attractor.
If anyone wants the album let me know and I'll upload it.
