I am not sure what the latest patch Version number is up to, but given all the time that Aaron puts into patching the game it is possible that one day the patch number will reach v2.0.
At that point, would the game still be SEIV or SEIV 2.0? Perhaps it will be called SEV?
What would a 2.0 SEIV be like? Will it have incorperated some of the fan ideas for improvements?
I don't know, but it should be interesting to find out.
