New Lenses Coming
The announcement dates for the following lenses haven't been confirmed. However, they will be coming sooner rather than later.
EF-S 18-135 II
This lens will have a silent autofocus motor geared to video. It will arrive with the new Rebel T4i. This has shown up in a US retailer inventory system. No price for the kit with the T4i.
EF 200-400 f/4L IS 1.4X
This highly anticipated lens will be officially announced shortly. The price will most likely be $10,999 USD.
EF 40 f/2.8 Pancake
I think it'll be EF, but a 40 f/2.8 Pancake lens is coming. Expect it to be announced either with the 5D or shortly after.
