I'm sorry, but Tim Cook is a lier. Back in 2013, Tim Cook specifically said that Apple will be introducing new products and product categories "across 2014." That quote should've meant that Apple has prepaid a set of new products that they were ready to introduce throughout 2014. However, here we are, in the second quarter of the year, and nothing new from Apple. Today's comment seems to be a confirmation that they still aren't ready to show us the new stuff by WWDC in June.
Seems like 2014 will be the exact same strategy for Apple as the years before; release every product you have within a month or two.
And I'm sorry, but your definition of a liar is the same as those who call a politician a liar for not living up to his promises. Lying requires an intent to deceive, which you cannot prove.
Across 2014 also does not necessarily mean "every quarter". You could see something launch in June, for instance, then another in September, then again in November...and that would be across 2014.
