Now looks like cherry to me.
Definitely. The buds are distinctive in size and shape as well as their growth pattern.
Pleased o not prune this until all the leaves are out next year, because with stone fruits such as cherries and plums, there is a high risk of a disease calle Silver Leaf entering wounds while the tree is dormant. This can be fatal to the tree.
Plenty of flower buds equals plenty of cherries too, so if you are wanting to save them from the birds, plan how you could make some fine net"sleeves" to cover branches once you have nice fat green fruit!!
