I'm hoping that Canon releases a new 300 f4 soon. I have the 300 IS and the non-IS. The IS system is clunky, whirrs, buzzes and the AF takes too long. If it didn't focus so close and take such great photos, I'd have dumped it a while back. The IS system failed and was replaced. CPS membership was worthwhile on that lens. My IS lens is as sharp as the non-IS lens but the non-IS focuses much faster, much like the 400 5.6.
If Canon develops a 300 f4 IS that has a modern IS system, I'll sell both 300's

Stop making good points, Canon might take them on board!

Just to support Fr3d's remarks, having worked in the tech industry I can say there is no mathematical correlation between filing and time to product arrival. Most never make it and I've seen an occasion or two where the filing barely beat product introduction. Overall, my impression is that Canon is rarely in a hurry

From someone working on patents, I would have to agree 100%
