I think Grimmjow must have got exceptionally stronger if he should have obtained a Segunda Etapa form in the +/- 18 months that have passed since we last saw him. And I think all Arrancar are able to enter and exit their Resurrectión as they want.

It appears that the one we all think is Grimmjow cut Kirge in half with his sealed Zanpakutô. To manage that, seeing as Kirge was strong, that would mean he's either gotten stronger, or just caught Kirge off-guard as he had his attention on Ichigo.

Regarding Uquiorra, I recall that the short chapter about his background shown in the UN-MASKED data book, stated that he was "born" as a Vasto Lorde, but I'm not sure. But I think his Segunda Etapa was just a higher and more powerful level of his Resurrectión, that only he had managed to reach. At least at the time he revealed that form.

Looking at the apparent power levels, Grimmjow was far weaker than Ulquiorra, and even though the latter was only ranked 4, he was (according to himself) the only one who had reached a 2nd stage in his Resurrectión. I don't think Grimmjow could have gained enough power to reach a 2nd stage, if Kubo doesn't change that.
