It seems to me that separating the pilot from the rest of the season would needlessly complicate things.
If the pilot is sold separately from the rest of the season, you would need to make two separate purchases to qualify for the end-of-season DVD (which would likely have both the pilot and the rest of the series on it).
Also, by making an upgrade discount available for the rest of the season, that creates a "special offer" incentive for people who already bought the pilot. Upgrade pricing is a strong marketing tool for Telltale already; they'll probably keep using it for pilots that lead to a full season.
