Now that there's a new healthy eating plate, will the healthy eating pyramid be no good?

Not necessarily. It us not so much a matter of the pyramid being no good anymore, as it is one of improving awareness in the setting of better information. The plate model is more understandable and easier to implement in practice. And it recognizes that food groups generally niter-relate more than fit into kaye's or steps. Speaking f pates - for health, portion control is key - so se smaller plates!
