Is that a sure thing? Rubleva/Shefer had a better Grand Prix than B/S.
B/S (19/20yrs) are younger than R/S(24/26yrs) and both the teams were received very well at grand prix events they did this year. Russian fed would very likely want a younger team to get some olympic experience. this result will allow them to send R/S to the worlds (D/S would very likely not compete) and try to keep the 3spots for the next world championships.
