I currently am a 15 year old who has taken on photography as a hobby. As of now, I own the following: T2i, 24-105 F/4L, 40mm F2.8 Pancake, 55-250mm 3.5-5.6 IS II, 18-55mm 3.5-5.6, a minolta Auto280PX flash and 2 Minolta lenses. I am a bit confused as to whether the 70D would be the ideal upgrade, or possibly holding off to the 7D Mark II!
I take pictures of my friends and RC cars. Currently, with the T2i I can definitely take pictures of people, but I find the camera really struggles with moving subjects. I know the T2i isn't really geared towards sports photography, and in my own experience I found this to be true. While taking pictures of RC cars I can only get about 40% of the shots actually in focus (AI Servo and center point) and it's a bit disappointing.
Here's an example of the RC cars:

Here's one that is out of focus:

They move VERY fast!
With stationary objects (people) there is absolutely no problem:

I am looking for something that will be able to get these shots in focus, have better low light focusing, and possibly better low light performance.
I have considered the following:
Don't do anything at all! (Parents would love this! :
)
Purchase a few fast primes. (Sigma 50mm f1.4)
Buy a Fujifilm X-E1 due to it's size and low light performance. Then down the road, buy a 7D Mark II or some "upgrade" to my T2i. <--- Most money spent here
Buy a Canon 70D during black friday. (No tax day at two of my local camera stores)
Wait for a 7D replacement
I really like the autofocus and video features that the 70D has (touchscreen!!!), as I like to make videos. However, with the possibility of a new 7D replacement that will only improve on the 70D (without the touchscreen and possibly wi-fi) I am really not sure if I should purchase anything at all! I'm not trying to sound like some rich kid, as I do work to get these items.
Maybe I should be grateful that I even own these items and hold off until I really need a camera. Thanks for reading!
If you guys need any more info, please ask!
