When will Marketo have responsive landing page templates?

Right now, we can send responsive email if we code it ourselves. It would be ideal if Marketo offered responsive email templates. Our Web site is responsive. BUT any landing page we would want to use in Marketo is not. Given the exponential increase in mobile use/traffic, this is a glaring omission in the Marketo toolbox. I have spoken to many Marketo customers who feel the same way. We fear the abandonment rate is far higher than it needs to be.

Thanks.
