If you are after either a Canon 300 f/2.8L IS II or 400 f/2.8 L IS II the good news is that B&H Photo announced they had some stock.
However because of the limited supplies of both the 300 f/2.8L IS II and 400 f/2.8 L IS II lenses by the time you read this article B&H have probably already ran out
Price wise the the EF 300 f/2.8L IS II costs will set you back $7,299 while the EF 400 f/2.8L IS II is a mere $11,499, which goes to show that even at this price these items do go out of stock very quickly, however it is easy to see why given the specs how could anyone resist.
Anyway stay tuned to this site and page for updates on stock availability on both pieces of glass.
The 400 f/2.8L IS II comes in a secured and cool box that when opened, you would in an instant identify if it has been tampered with.
