P4 extict!!?? Not for a long while if ever...it's ease of use, it's huge community for a start will ensure it's survival...I've upgraded to P5 (though it's not arrived in the UK yet) but I don't see it taking over for some time as there is much to learn in what appears to be a much more professional & complex app...now to me this is a good thing but to those who are happy with the ease of P4 or use it occasionally as a hobby it may be an expense they don't need...so as I look forward to unwrapping my copy of P5, I still say "long live P4" it will stay on my drive & be continually in use for many years to come :O)
