If they did ever announce a new shield, what would you need added to get one?

We always see rumors about a new shield coming out "soon".

The thing is, I don't really know what I'd need more that the 6 year old device doesn't already do

To be fair, I only stream TV and Kodi and watch things from a hard drive. So the shield is fast enough streaming and loads/plays from my storage fast enough for me

I don't know exactly how plex works but I don't really ever hear a lot of problems about that, but could be wrong

So if a new shield was announced, what would you need to get a new one?
