It's not clear from that paraphrase that ALL of anything will be available in the Beginner Box rules.
For example, it looks like it will only include four classes.
I am aware of the facts that:- we will have only 4 classes instead of 12 to choose from
- That we maybe only get to choose between 2 feats instead of 4 per level
- that maybe our cleric will just get to choose between 10 Level 1 Spells instead of 21.
- that the beginner box will again go up to about level 5.
I am completely fine with the choice of Fighter, Rogue, Cleric and Wizard, this is the "classic" adventuring party and a great entrance point for new and experienced gamers.
I would not want the full rules in the beginner box, too.
But I just hope to see the comlplete skill list including skills such as Entertain, Intimidation, Crafting or Survival (skills like these were not included in the Pathfinder 1 Beginner Box since the Skills list -though shorter compared to D&D 3.5- was still quite long) so we can have even more variety in playing the published adventures and designing our own ones.
