I wouldn't hold my breath. It's not for technical reasons, but rather cultural. I don't think Apple likes dealing with the enterprise IT market where customers badger them with questions about roadmap, support, etc.
IMO even if OSX and the PPC Xserves had been ready in the mid 90s, they definitely would have captured a larger enterprise market share (WebObjects too) but it still would have died off, like Sun, for the exact same reasons.
