> there will be a G5 version with JIT.

Now there:

"thanks to Fab the G5 executable is also available in the release package. [...] there were some murmur about the speed of the MorphOS version on G5 on some forums. No wonder: it needs a special version, which can be compiled from the sources for some time now. (Thanks to Tobias Netzel and to Fab for the special build.) Probably the same applies to the PA Semi processor"
