in the interim, visit the Blitz site and get some info on BlitzMax...
like i said above, the OSX version has already been released, the Windows version is soon to follow, and the 3D modules for these are slated to follow in the not too distant future as well...
you can look at the demo to get a feel for it and decide whether or not it's for you...
RealBasic... as far as 3D is concerned, a bit of a dissapointment... although some development can be accomplished using the default 3D plugin, any serious stuff would require you writing directly to OpenGL api... and after waiting for so many versions for them to improve the 3D aituation, i stopped licensing the updates.
the cross platform capabilities i think is questionable (using one codebase across multiple platforms), and i would choose wxWindows or one of the more matured apis like wxWin, that afford a wider scope and proven cross platform capabilities.
and if you are looking for a purely 3D cross platform game development environment (Win/OSX/Linux) you might also want to check out the well known Torque site
seriously though, Torque allows true cross platform game development with no porting issues whatsoever (my experience with win and osx only)... the same script and models need only be copied across and run...
a win version player can even log onto a mac version server, or vice versa.
i mean seeing as it has already been stated here that a MAc version is not in the immediate future, if cross platform is a must for you now, these are some options you might want to look into.
