Not necessarily.
I don't want to be the party pooper here, but "large adjustments" could mean anything. They could be changing the effects of our moves, for example, but leave the potency the same.
I fully expect TP to get a serious overhaul (or, at least, I am praying that it does). Enmity could use some work, so maybe our enmity modifiers are being adjusted. It wouldn't be the first time SE has done that one. There's also a few moves that have a lot of room for improvement. Divine Veil, Clemency, Tempered will, and Cover are all candidates for an overhaul of some kind.
I can totally see SE providing absolutely no dmg boosts to Pld, but making slight adjustments to their enmity. Changing Clem to scale with Skill Speed instead of Spell Speed, and providing some way for Pld's to regain Tp, then calling it a "large adjustment."
That said, your Pld can still breathe a little sigh of relief. The Vit/Str changes will mean that using Vit accessories will be the new standard for Tanks, and SE already said that Dps checks won't be as strict as they were in the last patch. So, even if they don't buff Pld Dps at all, you should probably take slightly less flak over it in the future ... not by much, mind you, but less.
