Dell Mini 11 Information Leaked or Just a Typo Error?

I am always amazed of the sharp eyes of people on the Internet. Apparently, Dell posted a series of accessories and on one of the accessory, a battery, it states that it is used for Dell Mini 10 and Mini 11. It looks normal, except that there is no mention of Mini 11 from Dell at this moment. According to Engadget, it could be a typo error for Inspiron 11z. What do you think?
