Actually, the new official road map is much different than the original one available at the time of launch at CES 2012. For instance, the company had initially expected to release a 14mm and 18-72mm f4 IS this year, followed by four more next year: 28mm f2.8 pancake, 23mm f2, 70-200 f4 IS, and 12-24mm f4 IS.
However, the 18-72mm is history, replaced by a more traditional (but faster than usual, as befits its class) 18-55mm f2.8-f4 OIS. The 18-72mm f4 zoom always seemed an odd choice to me; it would probably have been cheap, but not very desirable. This year's 14mm will be f2.8. And next year promises three primes -- a 56mm f1.4 lens, 27mm f2.8 pancake, and 23mm F1.4 -- and two OIS zooms, a 55mm-200mm f3.5-F4.8 and 10mm-24mm f4.
All of the lenses seem to follow the same design and feature conventions as the already-shipping lenses.
