Texas vehicle multi-year registration?

There was a mention here recently of a looks-like-it'll pass law that makes Texas a "single sticker" State, meaning that (if passed by the Texas House) vehicle registration and inspection sticker will become one and the same. Under that system, inspections are required YEARLY; and you can't get a reg. renewal sticker without it.

It may be that this will eliminate a previously existing option for multi-year renewals. This might explain the lack of such a choice on the website despite its still appearing on whatever form you got in the mail.
