No Blizzard. They were exciting when we all begged for then a year ago. Now they are just disappointing that it's taken you so long and you've only implemented them in the beta and we still have a month until we can use them for real.

Better late than never. Besides, I do think that blizzard is starting to actually care about SC2 in Hots. Compared to WoL, Hots is WAYYY better. They have put a lot more effort into improving Hots then WoL. I still have faith in blizzard. One more thing, we all know blizzard... late has always been their style.

It's not late it's just Soon™. What's the training mode like? Is it actually challenging or is it like all their other micro/challenge things that they had in WoL

The training mode is dedicated to teach new players how to play the game. Its not really "like" the other challenge things. It brings the new players through the basics of the game, step-by-step.
Husky did an interview with Dustin Browder a few weeks ago, where they mentioned the new training mode.

I believe the discussion of training mode starts around 13 mins.
