I don't know everything about it, but from my understand and with the amount of BTC donated for the cause, I think they can hire, brilliant engineers or even a company to do the job under a contract with real deadlines and stuff, right now only one person working on the new code?! hmm but again I can't judge since I don't know everything I guess more reading is due ^^
It's not just one person. It's at least two
. They have hired a company. Slickage Studios or something. Check the subforum in here and posts your ideas there.
