Wii Fit Being Prepared For US Release

We all know how obesity is a huge problem (no pun intended) in developed nations (in part due to all the gadgetry that makes life less inconvenient to move around), and Nintendo has released word that they are currently preparing the Wii Fit for a US release. Out in Japan for some time now (and being a runaway sales hit, mind you – shifting tons of consoles in the process), could this preparation mean translating the manual to English, or changing the weight limit that currently stands at 300 pounds? It would be really nuts for Nintendo to underestimate the weight of potential gamers and risk to lose tons of moolah in any case of a recall due to malfunctioning or broken units. 500 pounds would be a safer bet, methinks.
