Canon Rumors - Your best source for Canon news, rumors and creators

It's always so exciting to hear about new lenses and bodies. Many of use here are always wondering when new lenses and bodies are coming and its always so difficult to figure it out. Especially when you are getting ready to get new gear or upgrade your gear. At CR they post new patents very often and I get so excited to see what's coming next! There are usually at lot of detail about new goods but first thing they post is Patent release date and filing date. For example new 24-70L II's patent was filed on April 2009 and Published on October 2010. Is that mean it takes more or less 3 years to get a product to consumers or its up to Canon? It would be so nice if there are pattern that we can guess when we one is coming. Please let me know about what you think! Thanks
