It does indeed seem as though most people are quite negative about this. I actually I don't see this as being too bad, considering what phones are currently being sold. Here's my personal opinion on what's what at the moment:
520 = Biggest seller, but it's been out for a little while now. Has it already peaked, in terms of unit sales?
525 = Unfortunately only available in a select few countries, so it was never going to outsell the likes of the 520.
925 = Nice phone, not stocked everywhere now. Isn't really a first choice for people looking to buy right now.
1020 = Stunning phone as we all know, but was never a high volume seller and never will be.
1520 = Again, a brilliant phone, but at 6", it's not (at the moment at least), going to be a mainstream device with high sales. Also the cost keeps it relatively low in terms of units sold. This phone is also hard to get hold of in some regions and also exlcusives bite into potential sales numbers.
1320 = At 6" and still fairly new and not available in some regions, was never really going to show up on sales figures.
929 (Icon) = Maybe it would help if this phone actually gets released. I can see this being a very popular phone in the US. Trouble again though... carrier exclusive.
Windows Phone 8 itself = Other than the GDR updates, not an awful lot has changed. WP 8.1 can't come soon enough. New devices alone can't do all the work, if the OS is not keeping pace.
With the above, you can see why Nokia didn't have brilliant sales. Thinking about it, over 8 million sold is not actually that bad. Of course, looking at Androids mammoth amount of units sold it looks tiny, and is, but as far as Lumia's go, not too bad. The thing is, from this point onwards, it needs to improve quite a lot, every quarter. Starting from MWC in February, things need to get moving quickly.
The 929 needs to come out, and MWC needs to announce phones for the masses at decent prices. As much as I love the 1020 and in some respects the 1520 falls into this category, they are not for everybody and hence, the number of WP's in the wild does not increase enough. MWC has to focus on phones that will sell in numbers in my opinion. Examples could include a true 920 successor, a 520 successor and a 720/820 successor. The most important thing to do though, is have these available worldwide, at the same time. Don't make the Asian countries wait 2-3 Quarters longer than Europe or vice versa, get them in peoples mitts worldwide as soon as possible. Also, these phones all need to be running with WP 8.1 out of the box, when they get released.
It's easy for me saying it here. For it to really happen in the real world there are always obstacles such as logistics, costs, Microsoft takeover to think about etc. But unless things like this start happening, we'll just sit here with 8-10mil units sold each quarter for the whole year ahead. MWC and 8.1 can't come soon enough.
