Realistically, I have nothing to base my assumption upon, but the rumour about the A99 going to have an ISO hotshoe rather than an iISO one seems perfect in order to discredit rumour sites.
Four years ago, Sony upgraded their flash system to include wireless ratio flash with up to three groups. Last year they added an iISO hotshoe to a NEX camera - not an adapter for the existing NEX flash system. The A77 and A65 would have been prime candidates for a new hotshoe, because the number of A99s sold will not be enough to justify the development costs.
Most people who believe the rumour seem to be glad that their wish is finally coming true, so my guess is they simply want to believe it.
Time will tell if I'm wrong, but what do you think?
