0.8 - Will there be a <template if/bind>?

[Peter Wong]

After dabbling with 0.8, the lack of an `if` has lead me to write alot of imperative and error prone code... which is giving me alot of anxiety. :)

In the primer document (https://github.com/Polymer/polymer/blob/0.8-preview/PRIMER.md), there seems to be a planned migration for `repeat` (<template is='repeat'>), but I didn't see anything about `if` and `bind`...

So will there be an `if` and `bind`?
