Interesting idea, if entirely unsubstantiated :-)

Like GeneralAntilles, I was under the impression that Chinook would be the codename for maemo 4.x, which meant Diablo would be 5.x and Elephanta 6.x.

If Diablo is 4.1 after all, it seems odd to have a codename for a minor release; but if it's a major release, why not bump the major version number? If it's just OS2008 + WiMAX support, 4.1 makes sense (but not, necessarily the Diablo name). That'd make OS2009/maemo 5.0 == Elephanta.

Aha! They want to make Elephanta maemo 5.0 so that the initial letter corresponds to its position in the (English) alphabet. That'd make maemo 6.0 one of Foehn or Freemantle. What they do when they get back to "G" and can't use "Gregale", I've no idea :-)
