Anupam are you referring to the Premium version of 360 Total Security or a completely different version of 360? Haven't tried premium for 360 TS and not aware of a new version of 360. I found this link, which I think is what you mean:
Premium | Best Privacy Protection | 360 Total Security
If the firewall is glasswire, you will get access to the free version of glasswire in the free version of 360 TS. Otherwise, I can't say where they are going with the premium, but with the sandbox, document protector, and ransomware decryption tools all in the free (and others), not sure how much better premium could be. That said, the engineers at Qihoo seem pretty clever, so I wouldn't count them out of adding a few very nice tricks to the premium version.
Honestly, I am just happy they are making progress. The program is good, and a Chinese security program is good in the big picture, even if its primary user base is in the far east. Hope Qihoo can continue to grow while managing to keep their free product effective and updated, etc. I don't mind them making money for sure...
