Yeah, these consumer cameras are getting more and more awesome each year. I want one, but can't really justify spending any more on yet another camera.
I've shot with higher-end "pro-sumer" cameras for many years. These are cameras that overlap the worlds of the professional and amateur types. Really awesome gear in that class, but it's nice to finally shoot with a pro class body. Y'know how you can tell a pro from a pro-sumer? Well aside from the whopping difference in price, pop up flash built into body. Pro class cameras just don't have that. And they cost way more. Lol.
True professional class camera bodies assume that you're a serious photographer... and that if you want to fire a flash, you'll hook it up to the hot shoe, which is all that's available to you. I finally have a camera with no built-in flash. I feel so... professional! Lol.
Oh, and it'll be a good long, long, long, long time before we ever see a Mark IV. That's one of the advantages of rushing a model when it just comes out. And the recent release of the 5D Mark III was one of the most highly anticipated events in the photography world for quite some time. This wasn't just a tweak job and new model number... oh no. They pretty much redesigned the Mark II from the ground up in a sleeker form factor, higher res sensor, more extreme iso capabilities. So not only are you the envy of all your photographer friends shooting with previous models, you're shooting with lasting quality and technology.
And that's why the Mark IV isn't even on the minds of gear-heads and won't be for a long time. And no, I don't work for Canon.
Edit:
I remember a buddy of mine boasting about his full frame Mark II (which was considered the shit for quite some time) back when I was still messing with pro-sumers. "You can't beat that image resolution, bro." It's true. And now I have the Mark III! Ha! Eat it, photographer buddy! Eat it!
do you know me 
that clone looks perfect to me. The way i see it, Clone the healthiest fattest growing tips on the plant to get that extra boost of health and safeguard buffer for anything that may happen in the first few days/weeks.....If you clone from a lower branch where there is little light penetration there maybe more hormones needed to start making new roots, but the cell thickness of the leaves is not near that of the larger top leaves so the leaves will be more transparent and less efficient at photosynthesis. Again.....logic
