So, iv probably asked this before but i cant remeber so i'll ask now, does anyone know when some new Fourth Ed books are coming to the shelves

Supposedly there's one this quarter, one next quarter, and one 4th quarter. "This quarter" ends at the end of June, so hopefully in the next 7 weeks or so.

I found the FanPro Catalogue at the FanPro website (see page 2 for SR), it mentions their projected releases this year.
Pretty much like Shrike says, by the end of the quarter we should be seeing Runner Havens and/or Street Magic. But ya never know.

Thanks alot btw, been itching to know when some new stuff is coming since ya cant always intergrate some of the Aspects from third over
