Looks like they're keeping Philip around for the tour and will probably get rid of him at the first opportunity when they're down to the final 10. He's not versatile enough for the show, but he clearly has a fan base and would sell tickets.
I also thought Kupono had a weaker solo than Vitolio, but at this stage, it's sort of a toss-up since neither of them really have much chance in winning with Branden, Jason, Janette, Kayla and Randi on the show. Any of them could be in the top 4. Branden and Janette seem to be the clear front-runners, but anyone could make a fatal error and allow others to slip in to the front at this point.
