That has been a concern for me, too, but Round2 wouldn't reissue the AMC Gremlin kit (albeit in a slightly different guise this go 'round) a third time without knowing it has very good sales potential. Ditto for the '50 Chevy pickup which was reissued in Texaco livery (and with a newly tooled front "push" bumper IIRC) four or five years ago or so, and still holds up extremely well today. Seeing all of the RC2 era reissued kits reissued again by Round2 no longer surprises me, and I can't honestly say I'm disappointed, either. Eventually the (very) few I'd like to see reissued will be.
If what's in the box is the 1/25 Revell Jeep Honcho pickup with the 1/25 Revell Arctic Cat snowmobile from the "Ice Patrol" kit included, everything should match up scale-wise. Hopefully the snowmobile returns with some truck kit, as it's been a looooong time (197...9?) since it's been available. Still no 1/25 Monogram Chevy S-10, though.
Round2 acquired the Ertl tooling when they purchased what RC2 had, but it was mentioned (maybe on the Collector Model blog) they acquired none of the Ertl Agricultural molds-- M-F tractor, farm trailer, etc. RC2 already reissued the Transtar II Eagle cabover, so I'm pretty confident we'll see that one reissued in the next few years. The 4300 and KW cabover must've been fairly good sellers fro Round2 to run them again.
Sorry, just a pic I pulled from an eBay listing, but the kit was reissued by Lindberg a few years ago. It should be relatively easy to find, though I don't think the tires are the same as the original release.
The Michelin TRX tires might've been the best choice, depending upon which other tires they had to chose from, and how the wheels are sized. Granted, a second set of tires which better filled out the huge flares would've been ideal, but the TRX tires are in fact a true metric tire and debuted in '79 IIRC, so not terribly out of place on a first gen RX7. Was that really necessary? We "olds" will enjoy it, too.
