Canon cameras usually ship with any new firmware before it is released on their website, but there is no way to tell what version is on a camera without checking it, because there will always be some cameras in inventory that will not have it, sometimes for months depending on the dealer turnover, and on how carefully they are at selling older stock first. Ourlocal dealer has tags with the date of receipt from the manufacturer on each box which helps them. The cameras I've bought usually have a tag with 4-8 weeks before I bought it, but lenses can be a year if its a slow selling "L" lens.
It really does not matter in any event, since its user updatable, and a new version comes out from time to time.
