There are some more rumors that OS X 10.5 (Leopard) will be released at the end of March. I’ve come across a few sources reporting this same rumor.
With the release of Windows Vista, there’s going to be a lot more focus on what Leopard brings to the table and how it stacks up against Vista. Yes, we all agree that Vista “leveraged” a lot of features from Mac OS X 10.4 (Tiger) but I think Leopard will need to bring some more innovative features (other than the ones already revealed) to keep feeding the ‘pro-Apple’ momentum. Let’s hope those ‘top-secret’ features, that Steve Jobs mentioned, are killer-features.
Update (2/28/2007) I must say, my gut is telling me that Leopard will NOT be released in March but more likely in June. There really isn’t a benefit for Apple to release Leopard earlier and, I believe, Apple will want to coincide the release of Leopard with some updated hardware (like those rumored MacBook Pros) to garner some more hardware sales.
