Replying to Upgrade to 70d?

I am curious to see what newschoolers has to say. I have used a t2i for 2 years now, 75% for video, and 25% for photo. The things that appeal to me about the 70d are the price tag, the increase in fps burst, the better build quality, the swivel screen, the autofocus during video, and the buttons on the body of the camera compared to my t2i. I have thought about saving up for a full frame, but crop factor isn't always a negative to me. I also like the fact that I would be able to keep the lenses I own from my t2i and use them on the 70d. My plan would be to sell my t2i for around $300 and then only have to spend around $500-$600 in addition for the 70d. Is this a good plan, or should I be convinced otherwise. Let me know. Thanks!
