Rumor site says, TG-2 is coming

Not much to see yet.  The only bits of information yilded by googling (from mb2.com) are the upgrade in water-resistance (15m instead of 12m), and the same 12MP sensor and a "bright" 4x zoom lens (likely, unchanged from TG-1).  They mention "faster shutter speeds", but it could be just more marketing praise for the fast lens, rather than upgraded shutter (which would've been very welcome):

"A bright lens makes shooting at faster shutter speeds possible. Faster shutter speeds enable shooting at a lower ISO speed even during sunsets, poor weather conditions, dark rooms, and other situations where there is insufficient light, resulting in beautiful images with minimal noise."
