Here's Revell's 2015 line-up:
LINK!Wiederauflage = re-release
Neue Variante = new variant from an existing tool (probably utilizing some new sprues/parts)
Neue Form = new tool
Personally, I'm sorta underwhelmed.
Not much up my personal alleys. And I think a newly-tooled Hawk is a "waste" of a new tooling (presupposing there's only a limited amount of funding available for new toolings for any given year). A new Alpha Jet in 1/72, for instance, would've made more sense, I think.
New "early" Leopard 1 in 1/35 is cool, though. Rickshaw is gonna like that one. Should be far easier to make a "naked" cast turret Leo out of that sanding back the add-on armour mounting lugs on Meng's kit.
Although.... the bus rule seems to apply to new Leo kits as as well. Wait for ages, then several turn up at once (even if they're technically different versions). Couldn't one of them have gone for a new Chieftain instead?
