They're out. Kind of. You can buy the 32GB microSD card directly from SanDisk's web site. They cost $200, this way, but they do exist.

This is the limit for the SDHC format, unfortunately. It's not really a hardware issue... there's no good reason an SHDC card can't go higher. And maybe some will... SD cards were cut off at 2GB, but some 4GB versions were release, though they didn't work on all device. Most 4GB cards are SDHC. The different there is big: SDHC requires FAT32, and does block-oriented access (like a hard drive), SD requres FAT16, and does byte-oriented addressing (like memory).

The microSDHC cards at 32GB will be the maximum size for awhile to come, simply due to the space needed. The cards are only big enough for a single chip, so they expand by stacking chips. The 8-chip stack going into these new cards just fits in the 1mm space available (similar stacked technology, for use in devices like iPhones that don't use card memory, stuff 64GB in stacks of even more layers).

The main reason for SDXC is the file system: it officially requires exFAT (also known as FAT64), and will allow files larger than 4GB.

Some smart phones may be technically capable of upgrade to exFAT and SDXC support, there's no telling if any will release such updates. Palm did this -- the Motorola CPU they used on many of their PDAs and smartphones could support SDHC. Oddly, they did release support for the Treo 700p, but not for the Palm TX... despite the fast they used the same CPU. So there may well be similar games in this upgrade go'round.
