I didn't recognize Ei Aoki's name at first, but his resume is certainly notable enough for me and I would presume most people here. Incidentally the Troyka mentioned at the website is a new studio he and his friends founded late last year. This will be their first anime, made in conjunction with A-1.
No details yet except the mecha silhouette in the background, but the writer and director are enough to get my attention.
