Hmm... 
I don't think I will be interested. Yakuza 3 did a great (read FANTASTIC) job at explaining yakuza 1 and 2's story and that is all I would have got them for. I think I would be disappointed if I played it after playing yakuza 3 and 4.
But then I will also have a great knowledge of the yakuza universe, better than how it was explained in yakuza 3....
