Well; Freelancer (Oh my...evil MS) and Republic: The Revolution (small independant company) are pretty stable overall... and know what; they have no patches (Well, FL has 1; but that is only for MP servers)...
The GTA (and other R*) games are also pretty stable (altough I have noticed alot of complains... and a specific game-stopping bug in SA) and only became more so for the PC after 3.
So the only way to tell if it going to be 'buggy' is to see the product in the end; and even if there are bugs (which there are going to be) support may not even be needed afterwards; due to the low amount of infected people.
Anyway; Point of this all: Altough I ofcourse would hope and want support it all depends on the original IF said support is needed. Let's hope OE took a lesson of Kotor2's quite obvious (HK-50, swoop, Redemption?) bugriddenness...
