Java 5.0?

Sun appear to be renaming what used to be JDK 1.5.0 to J2SE 5.0 (link). Boy is this getting messy. I think they should just separate the branding part from the version part and call it Java 3. This makes more sense since they're almost certainly going to have to leave the internal version number at 1.5.0 anyway for compatibility.

I wonder whether Microsoft will come up with .NET 6.0 next? ;)
