I could be wrong of course, but that is probably never going to happen, there is not much incentive for devs/hackers to waste time on those models when there are already millions of hackable PS3s available to buy that have the same features.
This is just my opinion, Here is what i would do: Don't wait for a jailbreak/CFW for your model PS3, I would suggest you sell your current PS3 and buy a used slim (newest model you can find that is still jailbreakable), Either buy it already with CFW installed, or buy an OFW console and pay someone to downgrade and put CFW on it for you.
It will only probably cost you about 40-50 euro extra on top of what you get for your current ps3, and it will be well worth it.
