According to MMP's "News" page, It Never Snows is listed before Special Ops #3. Special Ops #3 is given a release date of August. So I'd guess July. Which probably means Christmas. Here's MMP's list:
At the moment, we believe the non-ASL games will be manufactured/produced in roughly this order...
No Question of Surrender - parts are in house and waiting for collation
Angola - slightly ahead of KoH, card decks due in next week, all other bits at various printers
Kingdom of Heaven - this and Angola could flip flop
The Blitzkrieg Legend
Kawaguchi's Gamble: Edson's Ridge
France '40 (somewhere mixed in above depending on how counters fit)
It Never Snows...
War of the Suns
Special Ops #3 (in time for WBC first week in August)
Stonewall Jackson's Way II
Storm Over Dien Bien Phu
Storm Over Normandy
