Sweetarama, that's a good plan. Should make the discussion about JP TFs a bit easier to manage too.
It really is super handy...living over here means TakTom releases are my 'normal' TFs, and there's not that many easily accessible release date sources. Until you put this up I was having to do regular web searches to figure out budget- and shopping-trip stuff, which can get to be sort of a pain.

One thing that may be relevant is that Amazon Japan still has Exhaust listed for a Feb 28th release. I'm not sure if that means the Amazon listing just hasn't been updated yet or if RobotKingdom (IIRC it was RK who announced the delay) et al are covering themselves just in case.
