Up close, the Tiger I and Sherman Firefly could kill it. At any real range though, another tiger II is the only thing that could kill it from the front, asside from the 190F8, and other large ord carriers.
When/if we get it, I say it be given a price of 75 perks at least, if not 100 or 125. Hell, maybe even 150 would be needed. What the 262 is for aircraft, the Tiger II is for tanks.
