X-Class Rollout and new XB10 Gateway

When I joined Xfinity recently I was able to order 1.2G/40M service.  Within the past week it has been updated to 2.0G/300M.  

I dislike making assumptions, but in this case it seems perhaps we are headed here to having X Class becoming available shortly.  According to an agent I spoke to, FTTH is not required to get X Class tier.  

Should this upgrade happen, would I be entitled to an XB10 gateway regardless of how recently my current gateway has been in service.
