As far as the rumours go they are definitely 'firming up' about a new Codex been released within the next 6-9 months...time will tell.
TLLC/DCCW Dreads make for a good all - round AT/AI choice, plus because they're cheaper than LR's you can fit more GK into a list, although the LR's are tougher to destroy. Mind you, that's sometimes a moot point because of all the Melta - spam been fielded these days.
In todays Metagame a pure GK list is probably a 3rd Tier list (mileage may vary), but hopefully that will change with a new Codex, but that may mean what you read in this thread might not be the ideal set-up..yea, that's like)
In the meantime if you are fielding Dreads only I would make them TLLC/DCCW ones for long-range anti-tank, or even take a ML arm instead of the DCCW on one.
If you are going to include any LR's, Crusaders are the way to go, especially if you are giving any of your GK Squads Incinerators..squads of 6-8 GK with an Incinerator out the front of a LRC is very effective.
All that said...currently the most competitive pure GK list uses only GK, GKT and LR's only, so zero Dreads, while the most effective and competitive list from the Codex as a whole is a pure DH list, so Inq/retinues w/2 Mystics and a shooty firebase, plus plenty of IST's w/ Melta & plasma, with everything is mounted in Rhinos....All of which may/will change with a new Codex.
Good luck with it all.
