Ya never know, But Ash is getting a pokemon with an Item evolution, and we have the huge Possibilty of the "Name of which we do not Speak", and that's a happiness evolution, So he might not, Then you also half to consider, If they didnt give Jessie, and Dawn the Pokemon they did, what else would they get?
Hey red i noticed a pattern that brock, dawn james and jessie have all have got pokemon that evolve by learning a specific attack and there are swinub 4 dawn speculation which is pokemon of same category so would ash get a tangela in future or swinub is going to come with ash. I know about 6 poke rule but you can't reject this fact. Now come to 2nd thought about tangela we know it is grass type as turtwig (same case as krabby and squirtle where squirtle was turtle that rival had as his starter). So could ash get a tangela that knows ancient power and evolve at first round of league. So what do you think. If you see a pattern make a thread on it.
