Shimano is building rear road derailleurs that are rated to take a 30t. A 32t cog rated rear derailleurs are rumoured.
The ten speed Tiagra 12-30 cassette has been out for a year and the Ultegra version is coming out by the end of summer.
Unlike Sram, Shimano is not abandoning road triple drivetrains. Sora, Tiagra, 105 and Ultegra versions are currently marketed and available.
Campagnolo will launch a new range of triples soon, including multiple 3x11 speed drivetrains;
"These will be Campagnolo’s first ultra-light, hollow-forged aluminum cranks. Three new triple cranksets will be available: Athena 11-speed in Deep Black and Bright Silver versions, Centaur 10-speed in Deep Black and Black-and-Red versions, and Veloce 10-speed in Deep Black and Bright Silver versions. Chainring sizes will be 30-39-50 (10-speed only) and 30-39-52 (11-speed or Centaur 10-speed)".

I would love to have a 30-39-52 chainring set with a 12,13,14,15,16,17,19,21,24,28,32 eleven speed cassette.
