If the brume 3 marketing still follows the security gateway road.
Then I think the hardware need to have much more processing power, the memory needs a increase the cpu is ok, but could be higher, on the other hand maybe arm is not the right cpu, but x86.
I'm aware IDS was on the feature notes, but then you also need to be more uniform with the hardware, snort for example asks alot of ram.
I think alot of consumers would expect this when they hear security gateway.
On the other hand, if that is not feasible, why not implement it as a extra matter controller for iot?
Then the marketing makes more sense, than just a few buzz words like iot, security to sound better, just my opinion 
The thing with this is, it is a little misleading these extra words can make a consumer assume there is something more than just a router, which the brume2 basically just is, no extra firewall things like IDS, I think that would be a missing chance for Brume3.
