New Canon DSLR and Lens Expected Availability

Here is a roll-up of the planned new Canon DSLR and lens availability dates that I am aware of:
 
Canon EOS 1D X
 
Canon Japan is stating "June 20, planned" for the arrival of this long awaited DSLR. Expect extremely limited quantities to be available for a long time. (thanks Kaz)
 
Canon EF 500mm f/4.0 L IS II USM Lens
Canon EF 600mm f/4.0 L IS II USM Lens
 
Both lenses are shipping now in the USA including from B&H and Adorama. But, supplies are extremely limited and only the earliest preorders are getting filled.
 
Canon EF 24mm f/2.8 IS USM Lens
Canon EF 28mm f/2.8 IS USM Lens
 
B&H just extended their expected availability date from June 17 to June 27.
 
Canon EF 40mm f/2.8 STM Pancake Lens
 
Retailers are not stating the availability date for this highly-anticipated lens. The USA press release says "end of June".
 
Canon EF-S 18-135mm f/3.5-5.6 IS STM Lens
 
The big USA retailers are not even showing this lens on their websites. The USA press release again says "end of June". Will these initially be available in Rebel T4i kits only?
 
Canon EOS Rebel T4i / 650D DSLR
 
The T4i bodies are now showing up on retailer's shelves in the USA. (thanks "D")
 
The bodies and with-18-55mm IS II Lens kits showed up at Amazon as I was typing this.
 
B&H lists the body and body w/ 18-55 II IS Lens as "Expected availability: June 18 2012".
 
Adorama is saying "Delivery scheduled to start June/18".
 
The Canon USA press release indicates that the Movie Kit bundle is expected at the end of June, but retailers are not listing the availability dates for this T4i version.
 
Canon EF 200-400mm f/4 L IS USM Ext 1.4x Lens
 
Don't ask.
