The basic translation would be, "I say to you today that you will be with me in paradise."
It has been commonly written, "I say to you, today that you will be with me in paradise," but "I say to you today, that you will be with me in paradise," is also a correct way to place the comma. Did you miss the part where Jesus said that he had NOT gone to His Father? He said that he had not gone to heaven until the disciples watched him go.
I can totally see your point... but I tend to lean towards something a little different based on other scriptural evidence... which would take a couple paragraphs to explain if you would like me to...
Main point being.. he was to be in Heaven even though no baptism could possibly take place.
