Absolutely not. The last album, Those Once Loyal (2005), was a masterpiece and while I respect the band for not making another album just to make another album.. I would really like another album!

Go listen to Memoriam, it's a sort of a successor band to Bolt Thrower. Even the name is a direct reference to Martin. Karl Willetts does the vocals and the sound is pretty much the same. It has/had other members from BT, then the rest come from Benediction and Sacrilege

They've put out five albums in six years (!), one recently

The Memoriam albums keep getting better as they go IMO, definitely worth a listen for BT fans. I got a patch from them recently and Karl mailed it himself and sent me a lovely hand written note and a signed poster. What a legend!

I can't see it happening, since Martin Kearns died they've done nothing and I expect it to stay that way. Perhaps they'll do the odd gig here or there, but tbh I'm happy not hearing a Bolt Thrower album with a different drummer.
