2.5/5/10gbit 60GHz?

Are there plans for 60GHz radios with 2.5/5 or 10gbit interfaces? We are looking between MT and Ignite units for a 60GHz rollout. If there are plans, will the units be backwards compatible? It would be great to have the option to go with wap/lhg 60’s now then just replace AP’s to gain new speeds and add CPE as needed.
