Preorder people have previews for the upcoming PsiEx. There's a lot of soulknife stuff in there. I'll give a brief rundown here: you can add and judge as you like, Psyren.

PsiEx: Find the Mark
Soulbolt - you trade your ability to form a mind blade for the ability to form what amount to arrows. You gain access to a different enhancement availability list and some unique blade skills.

PsiEx: Unlimited Possibilities
Gifted Blade - you gain limited manifesting ability starting at 3rd level. You choose your powers known off your list daily, plus additionally known powers (via Expanded Knowledge) stick around. Your ML is soulknife level -2. This ability replaces psychic strike. You gain up to 4th level powers off a limited list, mostly psywar stuff.

PsiEx: Master the Battle
Armored Blade - you can form armor the same way you form your soulknife. There's a slower enhancement bonus table, but the reshaping and enhancing features also apply to the armor. Also, your armor has an independent enhancement pool from your weapons, so giving your armor fortification doesn't mean you have to pull flaming off your blade.

Deadly Fist - you don't get a soulknife: instead, you get to imbue your fists with psionic punchiness. Enhancement progression still applies to your fists, too. You trade your bonus first level feat for IUS, but you also get the Flurry of Fists blade skill for free.

Shielded Blade - you get to form a shield the same way you form a soulknife. You get the Mind Shield blade skill free, but you also get to treat your mind shield as a heavy steel shield, so you can bash and things with it. It gains an enhancement bonus at the same rate as your mind blade, but you take a -1 enhancement bonus penalty for having both out at once. At 2nd, you get either Improved Mind Shield or Tower Mind Shield free. For this, you trade your first level bonus feat and your second level blade skill, which awesomely means that this is fully compatible with Armored Blade. Yes, you can now have a character that, as a full round action, can create armor, a shield, and a sword from nothing.
