Impact factor for Series B

I received yesterday the news from Thomson Reuters (via the Royal Statistical Society Executive Editor) that the Journal of the Royal Statistical Society Series B had an (ISI) impact factor of 4.63 over a five year period, which means a ranking as the third most cited Statistics journal after Bioinformatics and Biostatistics. The corresponding impact factor over a two year period is 2.21, which brings Econometrica in front of Series B. There is much to say about impact factors and their abuse in evaluations, but this is nonetheless a comforting indicator of the good performances of Series B, Indeed, I hope this will still be true five years from now since these figures reflect on the good governance of the previous editors, Anthony Davison, Rob Henderson and Andy Wood, not on mine!
