This would be fine if both factions were designed this way. But they are not. You don't always need hard counters, but when the german player gets hard counters, the soviet player can't return the favor. Having a late game that clearly favors one side does not make for good gameplay.
Look at vcoh, wehrmacht was waaaaaay more favoured in the late game back then, and everybody loves vcoh.
But soviet late game can be very strong too, with call in units for example.
What hard counters does ost player have then? A really expensive panther, that can be crippled on one well placed cheap mine and finished of by two at guns? I think soviet will be even more about using combined arms and proper unit placement, which i am really looking forward too.
But as people have said before, just play the patch fora couple of days first, because we basically can't say shit about it right now.
