Here is a copy of an email I received from him on this:

"I did know that they were working on the 85 f/1.2L and 50 f/1.2L that I told you earlier. Canon R&D is working on new DSLRs. We'll see 3D, successor of 5D and DRebel. I have no information about the 40D. They're also working on a series of non L wide angle lenses such as 24, 28, and 35. There're no plan, or I don't know, to replace 24L and 35L. R&D has many different groups working on different project. I only know one. So my information is only 70% accurate. Don't buy anything now especially the 30D and 5D. Dell is offering 25% off for the 5D. You should now why. The 5D successor is better than you can imagine. All DSLRs will have a big jump in performance. The pushed out the 30D just to buy time and fill the gap."
