I think it is too early to say too much - as it's going to be the server implementation of Sense that is going to be the proof of whether it is a truly excellent product or not. From what can be seen from the Desktop edition it is looking good though - I have been enjoying creating things in Sense. Qlik getting the licencing model right will also be critical.
Obviously there are a lot of things that QlikView can do that Qlik Sense can't at the moment. hic has indicated that some of these features will come across in time. The fact that there are some things that Sense can't do that QlikView can however keeps the distinction of what the different products are for. It's not necessarily that Sense should "improve" by having these features added - rather people should chose the right product for their needs.
In fact - I would spin it the other way around, that QlikView should improve to be more web-centric and have the latest charting features. This would then make the overall Qlik offering even more compelling.
Hope that gives you what you were looking for?
