Of course this happens shortly after I invest a lot of money in a lot of systainers. I was just telling myself the other day they will probably make a new version soon as the patents on the current version are probably about to expire. Maybe other companies will just start making T-lok style containers on their own once the patents are dead.
Updates are fine, but seriously, if you are going to make an announcement like this, tanos/festool needs to put out some explicit/clear information on the changes/compatibilities from the current model. It doesn't look like from a glance they are hugely different, maybe just some added aspects. But if form factor/interfaces/heights changed, that's going to cause heartburn for folks. I might rather see a side by side of the improvements/changes then "action photos" of them that tell folks nothing.
It looks like they added a front handle (makes sense on short ones I guess), rounded the corners instead of the chamfers. The Latch is different looking.
Down side is it looks like they down graded the label setup. I don't see side label holders. That sucks, as I put labels on on 3 sides. That was/is one of the really nice features.
