Here's the link to the video.
I mean, rumors on the internet are that Games Workshop is re-doing their line of paints, and presumably 145 is the number of paints. But... seriously? The video tells us nothing (it's just the number 145). A video on a line of paints is certainly better than nothing (and better than GW has done in the past), but given the efforts their competitors have put up as video teasers (say, the Privateer Press Colossal video?), this felt really weak.
Ah well, just noticed it, and it surprised me enough that I had to mention it.
