I'm not so sure the 60D is currently part of the Canon Loyalty Program. Have you called the number?
This is the page that has all the info, and it was updated only four days ago: https://photography-on-the.net/forum/showthread.php?t=948785
But it could be that the 60D is on there. You have to call to find out. They are extremely helpful. I've called a couple times and couldn't believe how well they answered every question I had.
In response to your question (should I upgrade): It really depends on what you're looking for.
If you're serious about video and will shoot a lot of video, then the flip screen will help a lot. If you really need the faster frames per second rate (like for shooting sports) then the 60D is a great upgrade. Plus, if you get into messy elements (dusty areas, drizzling rain, etc.) then the 60D is for you (I think it's weather-sealed....but I'm not exactly sure. The 50D was).
But if you're simply looking for better image quality of your photos, you won't get it. The 60D uses the exact same sensor and processor as the T2i. Your ISO performance, noise levels, colors....yada yada...those will be identical.
Personally, being the owner of a T2i, I'd love to have a 60D, but I don't need it at all. I don't shoot video (although I thought I would a lot when I first bought my T2i), I don't shoot sports, and I baby my camera when it comes to dirt, dust and rain.
I learned that my T2i is going to be my permanent camera until the day I go to full frame (which I would love to do yesterday, but until I find a sack with three grand in it, that's not going to happen in the next year or two).
By the way (just to add some confusing fun to this): Don't let anyone tell you otherwise: When it comes to shooting still objects (people, bridges, flowers, etc.), full frame is a world of difference. It absolutely blows crop away. People will argue with me and show samples till the cows come home, but the truth is that full-frame is spectacular. I visit this website (POTN) everyday for hours, and when I look at photos, 99.9% of the time I can tell if they are crop or full-frame. It's very rare that I see a photo and guess it to be full frame, and then find out it's not.
Full frame is the bomb. I can't wait to get there.
Thank you.
