The reasons for a new CFW...
1. 3K and 4K models
2. PSN Access
3. Eboot fixing is not just a hassle but more of a trial and error experiment (external, internal, mirror and what the hell not)
4. Playing backups of legit games purchased even after they are sold
(Example, I sold my copy Heavy Rain and later a Move Patch was released which I could enjoy as I had a backup of the game on my HDD
5. If there is a CFW, it should be released and not kept hidden irrespective of requirement as that is for users to decide same as devs can decide about releasing their stuff or not.
However, as the new CFW is supposedly said to be only for 3.55 users it is of no advantage whatsoever because of DEX. We need to address bigger challenges after 3.55.
That's my two cents
