May be once it becomes official product in the future , they'll get resources to finish it . It already took them 9 years to make this remake . They were short on resources . Luckily , now Valve have permitted them to release this game as official product , with price tag (it is free ATM) .
if it will come out full as full game with update source engine. it will be greatest remake of all time. well even incomplete is better than any remake.
