Haha i wish i could become a professional photographer, actually i study/work as graphic designer, and soon my work will be more photography-related.
Also, if i switch to the mkII(which i already played around with and loved it) i would choose the 70-200 f4 is.
comparing the two things would it be better a 70-200 2.8 vr ii on a d300s or a 70-200 f4 is on a mk II?

hmmm let´s put it that way:
Canon body = better , but

more expensive
Canon lens = worse or equal

less expensive
so if you switch to canon you´ll pay around 2800-3000 bucks and get a kickass combo. if you stick to nikon you´ll have a good body, but not so good as the canon one and you spend like 2000 bucks on a lens that should be abit better than the f4 IS, plus you keep all the stuff you already have.
as I said, if you feel like you´re much happier with canon products, consider the switch. if not, stick to the nikon stuff you already have and add lenses to your lenspark.
