Why is Biden waiting so long to make a decision?

For the 2004 election, he was Biden his time too. Although the decision to not run was made a little earlier; August 11.

Ok so now Biden says he will decide by either late August or early September, why doesn't he just come out and say he is running or isn't running? Why is he biding his time.

I think he wants to gauge what the public's mood will be to a Biden campaign. If Hillary is doing well and looks set to grab the nomination, a Biden campaign would no the Democrats absolutely no favors.
Consider the following scenario:
Biden joins the race and gets blown out of the water by Clinton. What that will signify to the general electorate is that the Democrats have rejected the Obama administration, and all the work the Democrats have done over the last two terms. This would also damage Clinton in the general election.

Its a smart move on Joe Biden's part, which is something people don't usually associate with the VP.

I'm sure he wants to carefully consider the decision, and feels it may be easier once his son's death isn't quite so recent.

Biden's time has come!

For the first time, the vice president looks like a more electable Democrat than Hillary Clinton.

Well, Sanders is also looking like a more electable Democrat. If someone's net favorables in Iowa and NH are around -20, they're probably not that electable.
