Mass Effect 2 Getting More Weapon DLC

According to a post written by BioWare senior marketing manager Jarrett Lee, Mass Effect 2 will be receiving what we can only assume is a set of weapon-only DLC prior to the release of Lair of the Shadow Broker. He wasn't willing to elaborate beyond that, though:
Hi everyone,

As Christina tweeted, some of the new guns you are seeing in those screens are not in the Lair of the Shadow Broker pack. They are in fact part of a different pack that will be released prior to Lair of the Shadowbroker - more details coming very soon. While this was simply intended to tease them I can see how it could be misleading, so I must apologize for that.

Lair of the Shadow Broker does, however, contain some *really* cool stuff we haven't revealed yet so stay tuned for more details as we head into August. And actually the very coolest part of the DLC (imho) will be something we absolutely won't reveal in the marketing or PR, to avoid spoiling it. I think most of you will find it to be our most satisfying DLC release yet for ME2.

Best Regards,

Jarrett
One thing the ME series could really use is more weapon diversity. How about some melee weapons or at least blasters/rifles/heavy weapons that can be configured with all sorts of different upgrades like we saw in the KotOR series?
