Nope, my 'conspiracy' scenario would be something like:
I'm guessing Wells still has whatever shares he has.
So it's more likely in my mind to be a sort of 'phased outage.'
Wells leaves now, prices keep going up.
Wells sells his shares in a years time.
Prices go up again. Kirby announces his impending retirement in a couple of years. Prices still go up. Kirby eventually retires, selling his shares, inflated due to the price rises shortly before his retirement.
Not long after that, the last price rise is shown to be truly unsustainable,
GW collapses in some form (eg bought by disney/hasbro etc), Kirby can go to wherever he wants saying 'hey, I kept the company afloat, what happened afterwards, not my problem.'
This all chimes with all the 'short term gains' sense I've got from things. Even Rick Priestley has made some comments in talking about his new
Beyond The Gates of Antares game that, while he can't argue that
GW is making money, their prices aren't good for the long term growth of the hobby.
