We'll have to see how this plays out. It's been very nice that Java's already available on all new Macs, but then there's been the dreadfully slow progress of incorporating updates, security fixes, and so on. On the other hand, OpenJDK has been building well on OS X for some time in both 32 and 64-bit forms. The only real missing pieces are easy ways to get OpenJDK builds installed (helped by Apple's restructuring of how they configure and locate Java installs) and the Cocoa-based backend for Swing (if you're using or building GUIs). In any case, there's lots of vectors to getting JDK/JRE on OS X, and this might actually make it easier to choose which vendor and version you want for your OS X Java install.
