Well considering the Forum Segment is "LIGHTING" and the description "Including Speedlites & other third party manufacturers" I think this would apply.
While the focus of the forums is on Canon, as it should be, photography and tools in general are discussed, and even... SHOCKER, lens, tools and accessories that can be used by CANON cameras.
Besides Lightroom deals,
Tamron 24-70 f/2.8 VC Announced
Tokina AT-X 11-16 f/2.8 PRO DX Ⅱ Lens Announced
Zeiss Distagon T* 25 f/2 ZE in Stock
Sigma 180 f/2.8 OS Macro Pre-Production Lens Goes Missing
CES 2012 Cool Stuff – Jobu Design Gimbal Heads
CES 2012 Cool Stuff – BETA Shell Cases
Sigma 180mm f/2.8 EX DG OS HSM Macro Announced
Adobe Lightroom 4 Public Beta Available
Sony Announces Their XQD Memory Cards
Nikon’s D4 Officially Official
So given this is an example just from 2012, having "non" canon rumors, announcements, is fairly common.
