Ordered mine Sunday from Canon, showed estimated shipping date of May 1 when I added it to cart but was backordered when I checked out. Showed as In Stock starting yesterday morning, but it hasn't shipped yet. Maybe today. The Canon store doesn't seem quite as responsive as Amazon and others. Things that are In Stock sometimes don't ship the same day. I gave up paying extra for overnight delivery if they were not going to ship it for a few days anyway. Had this happen with Adorama once as well.
Battery was listed as backordered when I purchased yesterday on Amazon, but got a notice to expect delivery next Tuesday so they must have a bunch arriving soon.
The $700 brick (similar to a $50 laptop brick) is only $399 on Amazon. You'll also need the DC coupler which lists for $350, only $249 on Amazon. Think I'll wait a while on these. Two batteries should be sufficient.
