In OTL they wasted a lot of money on useless light tanks that no-one really wanted. Partly because they were the only ones available off the shelf, partly because they hadn't a clear idea of what they actually wanted an armoured division to do.
Now thanks to actually continuing to develop after 1934, they have an idea of where they want to be. Not a perfect one, but at least they have an idea. That actually makes a huge difference in the availability of tanks - as someone who's worked on government aerospace projects, nothing slows things down more than a ministry who doesn't have a clear idea and is constantly changing its mind. The treasury is always an issue, but again, knowing what you actually want to do helps - the treasury is reluctant to give you money if you cant explain what you intend to do with it. It also helps with some of the back seat drivers who wanted THEIR view of tanks done, even if it didn't make sense - with a defined and approved part in place, its harder for them to gain traction with unproven theories.
Of course, timeline wise we are just ending 1936. Big changes wont be seen for quite a while - designing and building tanks takes time - but they are coming. The tanks may be a bit better - again, having an idea of what you intend to do makes the engineers job easier, and more likely to end up with what you want, but no Centurian yet.
