First off, members of this site and fans of the game are
not "
LOS'ERS"!
(Maybe "Legionnaires"?)
Secondly, the agreement I made with Romain regarding the digital version is that he would have complete artistic control over the new look while keeping the gameplay as close as practicably possible to the mechanics of the boardgame. He worked on many large computer game releases so he knows what he is doing and I wasn't going to second guess his choices for the medium and the platforms. That being said, it is an open question as to whether new designs for the digital board game would cross over into the real world.
The general consensus on the Forum is that a facelift is in order, even if the same basic designs are maintained to keep "the look" (for the Commandos, wolfhead helmet, big pauldrons; for the Nightmares, spindly goggle-eyed and grimacing with large greaves; and the glorious cow-headed, chicken-footed, flamethrowing, pitfork-stabbing look of the MkI).
That is a separate question from whether there should be a difference in game performance, and whether new figures should be released representing improved versions of the line troops.
If you want to keep the purity of the straight D6 system you have basically two choices: play with the ROF and kill numbers, or play with the range bands. If you are willing to accept an additional die roll - even for a minority of cases such as an exact hit or near miss (which only arise once out of every 6 rolls) then you have a lot more flexibility.
There are at least two reasons why new figures should perform better. First is that logically, new versions incorporate new technology specifically because they do perform better, Secondly is a matter of buiness necessity in that there won't be a great demand for new figures that are functionally identical to the old ones. They might catch the eye of some new players, and some established fans might want some more visual variation in their army, but I suspect that a new figure with improved performance will sell better.
Keep in mind that the LOS philosophy on point values is to represent, as close as possible, the actual combat value of a figure rather than some economic or arbitrary value that pushes you into an arms race (regardless of how historically accurate or business savvy that might be) so old figs will still be functional.
