There is a mix of Stuff, I would like to see for the World War 1 Range:.

German A7V Tanks (would take 5 Packs á 3 Tanks)

German Ehrhardt EV/4 (would take 3 Pack á 3 Cars)

French St.Chamond Tanks (would take 2 Packs á 3 Tanks)

British MKIV Female Tanks (would take 1 Pack á 3 Tanks)

Japanese Range (would take 3 Packs of Infantry and 2 Packs of Artillery)

Airplanes (would take 3 Packs, each with 3 different Models for Germany, Britain and France)

Decals (would take 3 Packs, each with different Markings, Numbers, Names for Tanks and Airplanes for Germany, Britain and France)

Good news and bad news here:

YES to Tanks and vehicles - more than you have listed.

YES to arircraft.

NO PLANS at all for Japanese or decals.   That's not a never, just a not in the current planning.

Overthinking it, WW1 Japanese can be proxied with early French. :D

Would also like to see:

German Büssing A5P Armoured Car (would take 2 Packs á 3 Cars)

French Peugeot M1914 Armoured Car (would take 2 Packs á 3 Cars)

British MKI and MKV Tanks

Experimental Tanks (Oberschlesien, K-Wagen, LK-I ect.)

Railway Guns

Armoured Trains

Rail Scenic Items

Trucks would be also awesome.

Remember that the British MKIV Tanks also need a Female Version.

As an extension to the WW1 range, any chance of morphing the range into the immediate post war Baltic/ Polish Soviet and Russian Civil War period, As far as I can see most of te figures are already now in place with just suitable types for Russian Revolutionary infantry and artillery required. I would suggest a pack of generic scruffy infantry militia/ conscripts, Greatcoated infantry in a mix of caps and the Bolshevik pointed budenovka.

Al the following are available as proxies:

Russian WW1 infantry as White Coloured regiments/ generic Russian troops.

Russian WW1 Cav and Cossacks as is.

Late War German Inf and cav as Freikorps

Italian WW1 and Austro Hungarian inf as Polish Regular Infantry/ WW1 Early British in caps as Polish Legion troops.

An armoured train and Lanchester./ Austin armoured car would be great though as well as the formidable Putilov armoured lorry.

I hope the above shows just a few packs of new figs would really open up opportunities for extending the range into this fascinating and largely untapped period.

Cheers Jon

Sorry, add-ons, Bolshevik cav in greatcoat and cap/ budenovka with lance and sword would bulk out the soviet cav, preferably with Tachanka for mobile MG support.

Other Stuff you could release are:

Spotting Balloons

A7V Flakwagen (Worlds first SPAAG)

A7V Funkwagen (Radio Car)

A7V "Nixe" (Only Famle Version with 8 MGs)

-Make them a mixed Package with 1x each unique A7V

Without sounding too much like wanting the world on a stick, would there be any uptake on a medical tent and orderly set, stretcher bearers, nurses, doctor and casualties as a table side vignette? This would be pretty generic for all countries I would imagine.

Also nice would be Prototype/1919 Tanks.

-LK II (24 Build 1918-1919 before send to Sweden and Hungary)

-MKVII (+20 Bild in 1920-1922 in the USA)

Also

What I miss in the German Range is the 3,7cm TaK18 AT-Gun and M1918 AT-Rifles.

Belgian Range (French Models but with a 57mm Field Gun instead the 75mm Mle97 Gun)

Please make the Early AND the Late Version of the St.Chamond Tank.

Love your line (which I just discovered), and can't wait for you to start accepting orders again!  I think 6mm is ideally suited for large scale (Corps/division) sized games, and for WWI that means a lot of artillery!  Very impressed with your current range, but would love to see even more- particularly some of the early war British pieces like the old 15lb gun, 5" howitzer, and 4.7" gun, the French Baquet system 120mm and Mle 1913 105mm and the later war heavies like the 9.2" howitzer and the French 220mm TR howitzer.
