Here is some unfounded rumors, originated from one source at sports.ru, who presumably have some access to Chrustalniy via connections with some athletes parents. She posted them yesterday. There aren't any proofs or other sources whether all of that is true or not - so take it as you will (apparently with HUGE heap of salt):
Judging by her other comments Alina's quad is 4Lz and in a better shape than it was before with 4F harness attempts. They postponed quads training then due to problems with her legs at the time - and now they start it over again. Alena jumps 3A without harness already. Here is link to source's profile where you can check all her posts

Also she claims that Alina jumps 4Lz in Japan now without harness to boot and reports about it to Dudakov via phone - and that talk was presumably overheared. It sounds very.. fishy. It's still possible though that part of these rumors is true. Anyway it triggered quite a discussion in Russian community already.
P.S.: also she said they don't want to advertise it yet due to toxic community and not perfect form in which these jumps are (so there are possibility that they won't include them in programs) - to not disappoint their fans too.
