Here are some of the High-level dungeons that'll be in FFXIV, if you haven't seen it yet.

It contains a few dungeons from 1.0 which were level 45-50, so not exactly on level 50+ like the crystal tower should be, but close enough.
These dungeons are:
Cutter's cry - with sand traps and frustrating puzzle rooms
Aurum Vale - with toxic pools and poison gas
Dzemael Darkhold
You've also got some new places such as:
Amdapor Keep - looks to be a gathering place for the Cultists kown as "The lambs of Dalamud"
The Stone Vigil- An Ishgard stronghold that's either been overrun by their enemies the Dragons and their ilk
Sunken Temple of Qarn
The Wanderer's Palace - Tonberries... need I say more?
Not sure what level the new ones are, but most likely higher than Haukke Manor at least.
What Yoshi probably means is adding more dungeons for the 50+
