Agreed. The wording is weird and confusing.If this is real, shouldn't the message read "Should old acquaintance be forgotten..." instead of "Should old acquaintance be forgot..."? I guess Apple's done this before with "Think Different," though.
I believe this invitation's fake, but I do think it's very likely that Apple will host an event between now and March.
It took all of 5 seconds looking at it to determine it's an obvious fake. There's a number of imperfections, not to mention the different typeface (no, it's not unheard of for Apple to change it, but still).
