A couple of possible answers
(a) Nobody knows. Prices can do anything in the short term.
(b) Six months from now, $440.522 per B share in today's money.
It's likely that one of those is a little less precise (though more accurate) than you would like, and the other a little more precise (but less accurate), so just interpolate to taste : )

Second answer is a six month extrapolation of the 20 year trend line of log real book per share, times the 20 year average trailing P/B ratio, all at CPI 320.8
So, barring better knowledge, it's a sensible starting guess.
