My personal opinion is that DF-41 will be most likely armed with one DF-31 RV, and since it's a larger missile it can reach US no matter where it's launched. Currently DF-31A with it's 100-300kt warhead needs to be deployed in certain areas to reach every target in US, but larger missile would remove such problems. If DF-41 is armed with 10 warheads (claim made by Gertz) then it must be one massive missile.... probably bigger than Peacekeeper MX. Remember that back in 1996 (before DF-31A emerged) NAIC estimated that DF-41 would be armed with three 470kg DF-31 RV's.
People who claim that DF-41 is armed with 10 MIRV's all have some sort of agenda. Some are western warhawks like Bill Gertz, and others are Chinese ultra-nationalist who want to believe in Georgetown University "report" that PRC has manufactured up to 3000 warheads... it makes them feel all warm & fuzzy inside.
50 missiles with one warhead each is better (not too any eggs in one basket) than few missiles with many warheads.
Use five of your own warheads to destroy one mobile ICBM with 10 MIRV's and you have hit the jackpot, but if you have to use same amount of warheads to take out mobile ICBM with only one warhead and there is 50 other mobile ICBM's somewhere...
