Actually, Matthew has mentioned plans to revise everything eventually.
I based my statement on what has been officially announced at this time. I assume that he wants to update everything over time.
I should point out, that is in the context of a ten year span and I would merely not wish to rule anything out
Ten years?! I'm gonna fire up a Kickstarter to send you guys some coffee or Red Bull or something. See if we can't cut that down a bit. :coffeegulp:
