I can see it now... the next Live Letter:

"We are also pleased to announce a high-resolution texture pack! There is a free option that offers upgrades for ARR map textures only, and a $5/mo 'Premium' version offering HD textures for everything in the game. We are also introducing a new currency, Texture Nuts, that allow you to unlock 4K textures for one map, for one day. Free versions grant one TN per day, while the premium version offers two TNs per day. Look forward to it!"
