Yes, it does - though in Atlanta traffic it was far from accurate. LOL! And it is better about showing what lane you need to be in on a multi lane interstate like Atlanta has. The best way I've found to get it to 'recalculate' is to push the back arrow and select recent destination.
Yes - it displays estimated time of arrival in lower left corner and updates it as your timing changes due to traffic slow down - change of course, etc. I also agree with one of the other responses - it does a much better job of warning you what lane to be in than my older one did.
