Are tracked skid steers gaining on wheels for snow?

[sea2summit]

Trying to decide on which way to go and last time I gave a hard look the prevailing opinion was wheels were the way to go if you had to deal with snow. Now it's looking like there are new track tread patterns and suspension more favorable or comparable on snow. ASV seems to really be pushing tracked units on snow and they seem to have a solid background with snow.
Thoughts/opinions?
