For now, HP networking seem to be fairly actively developing the Procurves with the new ASICs.The Openflow stuff is leading on Procurve, for example. They've rationalized the range a bit, particularly at the low end (web/unmanaged) but I doubt they are ready to bet the business on the H3C stuff any time soon. In the longer term, who knows?
I think a lot of people like Comware because it's more familiar coming from a Cisco background.
