I enjoyed the Beta as well, although it was not without flaws. The best I can say is that it is a lot of fun, but if you want to play it as a single player I think you will get annoyed very quickly. The Republic classes may need more balancing, I played as a smuggler and many of your class skills require using the cover system which can be dodgy and wastes time.
Most important, if what you love about KOTOR was meaningful choices, character customization, gameplay mechanics... you will likely be disappointed by TOR, at least at first.
