Simple.....Phase them out and replace them, starting with the worst models and particularly those that are likely best sellers if redone properly, then throw in the odd 'Airfix Special' to liven things up (ie: do exactly what they have done so succesfully with their old 1/72 aircraft range). I'd suggest something like this: 1/72 M4A4 Sherman V 1/72 Panther Ausf A - Main Production Series (massive yawning gap in the market, Revell & Italeri are utter rubbish, Dragon have taken a lunge but based on their CAD their forthcoming kit is junk too) 1/72 M4A4 Sherman Vc Firefly (Tulip RLs included for Guards Armoured) 1/72 Bergepanther Ausf A mit FLAK.38 (only available as resin conversions and you need two of those, plus OKB tracks to build an even vaguely accurate one) 1/72 Sherman Crab 1/72 Panther Ausf A - Early Production (with a Borgward would be great) 1/72 Hamilcar Glider & Tetrarch Light Tank.....This would be the 'Airfix Special' I said I don't go in for wishlists and TBH, while this might closely resemble one, it really ain't one.....But it does suggest how, with careful investment in just a couple of high quality tools, Airfix could jump into the 1/72 AFV market as a serious player, with a chunk of the market all to themselves. Airfix reputation in the 1/72 aircraft world has been literally transformed over the past decade and I can see no reason why Airfix couldn't do the same in the Braille Armour field too, if they so desired.
